One Turn Kill Axim Core Deck
Build a reliable One Turn Kill Axim Core deck with Swift Thunder+, Laevateinn+, Oxalis Prayer+, and a clear opening-hand and combo plan.
A One Turn Kill Axim Core deck lives or dies on sequencing. The difference between a clean kill and a stalled turn is usually draw discipline, cost reduction, and one well-timed buff on a multi-hit attacker. This guide breaks down a complete One Turn Kill Axim Core deck skeleton, explains why each card earns its slot, and shows how to play the line without guessing.
Why This One Turn Kill Axim Core Deck Works
The core idea is simple: Swift Thunder+ starts the draw chain, Oxalis Prayer+ stops that chain from becoming a deck-out risk, Nergal's Experiment+ raises the attack value of your key cards, and Laevateinn+ turns the setup into a multi-hit kill. Assassin's Sign+ and Double-Edged Sword+ cover the damage gaps that appear when enemy HP climbs or when the main line falls short.
The deck is not a blind all-in. It is a counted all-in. Every copy count is chosen to make the combo reproducible even when one piece sits near the bottom of the deck. Three copies of Swift Thunder+ and Laevateinn+ keep both the opening and the kill consistent. Two copies of Oxalis Prayer+ are enough to find the cost reducer, while a third is a reasonable luxury if you have room.
| Engine piece | Job | Why it matters |
|---|---|---|
| Swift Thunder+ | Main draw engine | Starts the chain and digs through the deck |
| Oxalis Prayer+ | Cost reduction | Lets you stop drawing after the hand is assembled |
| Nergal's Experiment+ | Attack buff | Pushes Laevateinn+ past higher enemy HP |
| Laevateinn+ | Multi-hit damage | Converts setup into the main kill |
| Assassin's Sign+ / Double-Edged Sword+ | Cleanup | Covers damage gaps and low-deck finishers |
One Turn Kill Axim Core Deck List and Copy Counts
Every slot in this One Turn Kill Axim Core deck has a job. The list assumes all cards are upgraded, and card upgrades unlock by playing through the game. If your upgrades are still coming in, use the closest versions you own and keep the same priorities: draw first, cost reduction second, buffs third, finishers last. Do not force the full One Turn Kill Axim Core deck list before the key upgrades are available.
| Card | Key effect | Copies |
|---|---|---|
| Swift Thunder+ | 3 cost, 25 damage; fragile; adds another Swift Thunder+ to hand | 3 |
| Laevateinn+ | 3 cost; 15 damage x 3 hits; attack count scales with 3-cost cards played | 3 |
| Oxalis Prayer+ | 1 cost; reduces all hand costs by 3; discard 1 | 2, with a third as a reasonable option |
| Nergal's Experiment+ | 3 cost; gives +15 attack to 2 cards in hand | 3 |
| Assassin's Sign+ | 5 cost, 20 damage; 50 damage at 5 or fewer deck cards; 100 at 1 or fewer | 3 total with Double-Edged Sword+ |
| Double-Edged Sword+ | 0 cost, 60 damage; using it gives -10 attack to cards in hand | 3 total with Assassin's Sign+ |
| Backdoor+ | 4 cost; replays the skill used immediately before | 3 |
| Roaring Thunder+ | Adds 3 Swift Thunder cards to the deck; cost not listed | 3 |
Swift Thunder+ is the strongest general-purpose draw source in the build. It is fragile, so play it before other cards whenever possible. Laevateinn+ is the main damage source because it offers higher total damage than a zero-cost multi-attack option, even though it requires an action to attack. Nergal's Experiment+ becomes more important as enemy HP rises, since Laevateinn+ alone may not clear the bar in later fights.
Oxalis Prayer+ solves a specific contradiction: after digging deep with Swift Thunder+, you do not want to draw more, but playing cards still costs resources. Oxalis Prayer+ reduces hand costs by 3 and discards one card, making most of the adopted cards zero-cost or close to it. That is how the deck stops drawing without losing the ability to finish.
How to Play the One Turn Kill Axim Core Deck Combo
Start by finding Swift Thunder+. Play it early, before other cards, because it vanishes when other cards are used. If Swift Thunder+ is missing from the opening hand, Assassin's Sign+ can serve as the fallback draw source. Keep at least one card in deck; the line wants to dig deep, not to hit zero.
Once you have enough cards in hand, play Oxalis Prayer+. It reduces the cost of all cards in your hand by 3 and discards one card. That cost reduction is what lets you stop drawing and still pay for the combo. The cost-reduction and draw loop is the engine that makes the rest of the sequence possible.
Then buff Laevateinn+ with Nergal's Experiment+. Nergal's Experiment+ adds +15 attack to two cards in your hand, and Laevateinn+ is the priority target because it is your main multi-hit attacker. As enemy HP rises, this buff becomes essential; Laevateinn+ alone may not deal enough damage in certain situations.
Finally, attack with Laevateinn+. Its base line is 15 damage across three hits, and the number of attacks increases based on how many times you have played 3-cost cards. Play your other 3-cost setup cards before the final Laevateinn+ swing when possible. If damage is still short, use Assassin's Sign+ or Double-Edged Sword+ as a finisher.
| Step | Play | Why it matters |
|---|---|---|
| 1 | Swift Thunder+ or Assassin's Sign+ fallback | Starts the draw chain; keep deck count above zero |
| 2 | Oxalis Prayer+ | Reduces hand costs by 3 and discards 1; stops forced draw |
| 3 | Nergal's Experiment+ | Gives +15 attack to 2 cards; target Laevateinn+ |
| 4 | Laevateinn+ | Main multi-hit kill; play other 3-cost cards first |
| 5 | Assassin's Sign+ or Double-Edged Sword+ | Cleanup finisher if damage falls short |
Opening Hand and Sequencing for the One Turn Kill Axim Core Deck
A strong opening for the One Turn Kill Axim Core deck usually contains a draw engine and a way to stop drawing once the combo is assembled. Keep Swift Thunder+ aggressively; without it, the deck can stall before it reaches the cost reducer. Oxalis Prayer+ is the next priority because it prevents the draw chain from forcing unnecessary cards. Laevateinn+ and Nergal's Experiment+ are the damage pair, so keeping one of each is reasonable when the rest of the hand supports them.
Do not keep a hand that needs several expensive cards without draw. The deck can win through redundancy, but it cannot win through a hand that never starts. If you have to choose between a second finisher and a draw piece, take the draw piece. The combo needs cards in hand more than it needs extra damage.
| Priority | Card | Keep when | Why |
|---|---|---|---|
| 1 | Swift Thunder+ | Almost always | Starts the draw chain |
| 2 | Oxalis Prayer+ | With draw or a low-cost hand | Reduces hand costs by 3 |
| 3 | Laevateinn+ | With draw or Nergal's Experiment+ | Main damage source |
| 4 | Nergal's Experiment+ | With Laevateinn+ | Adds +15 attack to key cards |
| Fallback | Assassin's Sign+ | No Swift Thunder+ | Backup draw and finisher |
Sequencing matters more than raw card count. Play draw first, stop draw with Oxalis Prayer+, buff before attacking, and save the finishers for the moment when Laevateinn+ cannot close. If you play the finishers too early, you lose the damage they provide when the deck is low or when the main attacker falls short.
Flex Slots and Safety Plays
Backdoor+ and Roaring Thunder+ are the safety valves. Backdoor+ replays the skill used immediately before and can access skills that require choosing from three options before or after battle as cards. With the duplication skill, two zero-cost Backdoors can create a stall loop against a card-sealing fourth-battle encounter, which makes a bad checkmate easier to avoid. Roaring Thunder+ adds three Swift Thunder cards to your deck, giving you a fresh draw pool after an enemy cost-increase attack punishes a deep dig.
These slots are not the main damage plan, but they are not filler either. Three copies of each are fine because there is no strong reason to cut them, and the deck benefits from seeing them in fights where the main line gets disrupted. If you must trim, trim a luxury Oxalis Prayer+ or a redundant finisher before you cut the safety package.
| Finisher | Condition | Damage note | Best use |
|---|---|---|---|
| Assassin's Sign+ | Deck has 6 or more cards | 20 damage | Early fallback or draw source when Swift Thunder+ is absent |
| Assassin's Sign+ | Deck has 5 or fewer cards | 50 damage | Low-deck finisher |
| Assassin's Sign+ | Deck has 1 or fewer cards | 100 damage | Last-card closeout |
| Double-Edged Sword+ | Always | 60 damage; -10 attack to cards in hand | Zero-cost cleanup |
| Laevateinn+ | After buffs and 3-cost plays | 15 damage x 3 base, with attack-count scaling | Main combo kill |
FAQ
What makes this One Turn Kill Axim Core deck consistent?
The consistency comes from redundancy. Three copies of Swift Thunder+ and Laevateinn+ make the draw engine and the main attacker easy to find, while three Nergal's Experiment+ and two Oxalis Prayer+ support the setup. Assassin's Sign+ adds a backup draw source and a low-deck finisher.
Do I need every card upgraded?
The list assumes full upgrades, and card upgrades unlock by playing through the game. If you are still unlocking them, use the closest versions you have and prioritize the draw and cost-reduction pieces first. The One Turn Kill Axim Core deck can function below the full target, but it will be less consistent.
How do I avoid decking out?
Keep at least one card in deck at all times. Draw with Swift Thunder+ until you have enough resources, then use Oxalis Prayer+ to reduce costs and stop drawing. If an enemy raises costs after a deep dig, Roaring Thunder+ adds three Swift Thunder cards back to the deck.
Can I cut Backdoor+ or Roaring Thunder+?
You can, but you lose specific safety coverage. Backdoor+ supports skill replay and duplication loops, while Roaring Thunder+ protects the draw pool after cost-increase pressure. If you cut them, replace them with draw or finisher redundancy rather than random high-cost cards.
