Strategy Guide-Rated Builds & Proven Tactics
This is NOT chess. It's a deckbuilding roguelike that pretends to be chess. If you approach it like a chess game, you lose. If you approach it like Slay the Spire with pieces, you win. This guide is built on that principle.
Opening Builds-Ranked & Explained
Three proven openers. Pick one per run and commit.
Build #1: Knight Aggro
| Step | Move | Why |
|---|---|---|
| 1 | Develop both knights to center | Knights on d4/e4 dominate 4x4 and 6x6 boards |
| 2 | Pawn push to clear diagonal | Opens bishop + clears knight’s second L-jump |
| 3 | Knight+Bishop Combo Gambit | Maximum reach-threaten 6+ squares simultaneously |
| 4 | Makibishi’s Gambit | Captures drop trap tiles on the defender’s square |
| 5 | Checkmate with knight+queen | Finish before opponent’s board develops |
Best against: Non-boss boards, Botezarro, Hikarul the Banished
Weak against: Queen-heavy boards (a queen eats aggressive knights), Tal the Cursed
Pro tip: On 4x4 boards, Knight Aggro can win in 4 moves against the AI. Open d4 knight, e4 knight, then drop a Makibishi’s trap on the defender’s escape square. The AI rarely responds in time on boards smaller than 6x6. This is your speedrun opener.
Build #2: Pawn Wall Defense
| Step | Move | Why |
|---|---|---|
| 1 | Push center pawns (d4, e4) | Control the only squares that matter |
| 2 | Develop bishops behind pawns | Ranged support while pawns block |
| 3 | Keep a Protective Tile on the king | King safety and economy protection |
| 4 | Sacrifice for Strength | Turn pawn wall into mobility buff |
| 5 | Promote a pawn with Race Flag’s | Endgame conversion with a gold payout |
Best against: Boss fights (survives longer), Queen Gambit
Weak against: Aggressive AIs that punish slow development
Pro tip: Pawn Wall + Templar’s and Banner’s protection creates an exploit where the AI wastes ALL its Gambits trying to break through. The AI prioritizes your king, but when it’s protected AND walled, it will burn 5+ Gambits on futile attacks while your bishops destroy everything from behind the wall.
Build #3: Economy Rush
| Step | Move | Why |
|---|---|---|
| 1 | Play safe, minimize piece losses | Every lost piece drains the gold you buy it back with |
| 2 | Bank cash with Berserker’s, Squirrel’s and Bug Catcher’s | Capture and pawn payouts compound your first big win |
| 3 | Buy gambit tokens | A cheap token mid-run finds an economy Gambit without a full shop budget |
| 4 | Buy S-tier Gambits in bulk | Out-gear the opponent |
| 5 | Win through raw card advantage | 5 Gambits vs their weaknesses = auto-win |
Best against: Boss prep runs, long campaigns
Weak against: Early aggressive AIs that don’t let you farm
Pro tip: The shop always shows the next boss mechanic in the bottom-left corner before you spend a coin. Reading it first is the cheapest edge in the game: it tells you which Gambits are worth buying and which are a waste this run.
Advanced Gambit Combos
Combo #1: The Assassin
Cards: Makibishi’s + Silver Fork’s + Berserker’s
- Move a knight so it threatens 2+ pieces for the Silver Fork’s roll
- Trade into the defender with Makibishi’s dropping a trap tile
- Silver Fork’s skips the enemy turn when it connects
- Berserker’s pays out as your first capture lands
Win condition: Tempo swing with a trap left behind
Combo #2: The Reposition
Cards: Jump’s + Wrecking Ball’s + Berserker’s
- Leap the rook over holes and gaps with Jump’s
- Rebuild the rook threat down the open file
- If the rook ever dies, Wrecking Ball’s hands you a king
- The swing lands in one clean move
Win condition: One move generates 5+ turn value
Combo #3: The Comeback
Cards: Lemming’s + Throne’s + Queen Ant’s
- Open with Lemming’s for a free pawn
- Promote with Throne’s so the board gains a king
- Farm pawns with Queen Ant’s for gold, then buy back the dead with Battle’s
- Buy back the fallen at the Graveyard
Win condition: Full roster rebuilt from gold
Combo #4: The Boss Killer
Cards: Berserker’s + Throne’s + Dark Knight’s
- Read the boss mechanic in the shop preview before you spend anything
- Bank gold early with Berserker’s on first-capture turns
- Bulk up with Throne’s and Dark Knight’s damage reduction
- Drop a trap tile on the square the boss must use to reach you
Win condition: The boss spends its cooldowns while you out-sustain it
Deck Composition Math
| Deck Size | Consistency | Play Style | Recommended For |
|---|---|---|---|
| 12-18 cards | Tight and fast | Hyper-aggressive | Speedruns, 4x4 boards, experienced players |
| 19-25 cards | Best consistency | Balanced | Most players, most runs-this is the sweet spot |
| 26-35 cards | Slower draws | Control/late game | Boss runs, new players learning |
| 36+ cards | Diluted | Unfocused | Avoid-dilution kills consistency |
A focused 15-card deck of S/A-tier Gambits beats a 35-card deck with mixed tiers every time.
THE GOLDEN RULE OF DECK SIZE
Every Gambit after #22 reduces your chance of drawing your best 5 Gambits. A bloated deck isn’t versatile-it’s diluted. Keep it under 22 cards unless your build specifically requires more.
Reading the Board-Phase by Phase
Turn 1-8: Development
Focus: Get 3+ pieces into active positions
- Knights first, then bishops, pawns for coverage
- DON’T bring out queen before turn 5
- Count enemy Gambits used-they burn them faster than you think
- If you’re behind after 8 turns, the board was wrong for your build
Turn 9-20: Execution
Focus: Coordinated attacks, Gambit chains
- Look for 2-in-1 capture lines (Silver Fork’s + Makibishi’s)
- If ahead: simplify. Trade pieces 1:1.
- If behind: create chaos. Leap a piece with Jump’s.
- This is where most games are won or lost
Turn 21+: Endgame
Focus: Checkmate or survive
- Push pawns to promotion-it’s your best path to victory
- King activity matters now. Move king toward the action.
- If winning: ladder mate with rooks
- If losing: stall, look for comeback Gambit
Boss Fights: Special
Focus: Pattern recognition over aggression
- Scout first move (throwaway piece)
- Track boss Gambit cooldowns
- Time your defensive Gambits for the specific turns they matter
- Survive > Kill fast. Bosses have limited Gambit pools and WILL run out.
Tilt Management
THE 3-LOSS RULE
If you lose 3 runs in a row, STOP. Your decision-making is compromised. Take 10 minutes, review one replay, identify exactly which Gambit you should have bought instead. Come back fresh.
Common tilt mistakes:
- Buying expensive Gambits out of frustration
- Rushing into boss fights under-prepared
- Ignoring shop rerolls when your build is stuck
- Playing the same opener after it’s clearly not working
