Chaining

When one activation triggers another, you have a chain. Chains are potentially infinite and resolve backwards.

What Is a Chain

A chain occurs when card A's activation triggers card B to activate (or reactivate), which in turn triggers card C, and so on. There is no limit to how deep a chain can go.

For the distinction between activation and reactivation, see Activation & Reactivation.

Resolution Order

The rule is: last triggered, first resolved. When card A triggers card B, you fully resolve card B's activation before returning to card A. This is stack-based resolution:

  1. Card A activates.
  2. Card A's effect triggers card B to activate.
  3. Card B's full activation is resolved now.
  4. Card B's effect triggers card C to activate.
  5. Card C's full activation is resolved now.
  6. Return to card B (if anything remains to resolve).
  7. Return to card A (if anything remains to resolve).

Stack diagram showing chain resolution: three cards (A, B, C) stacked vertically like a call stack. Card A triggers B, B triggers C. Arrows show: C resolves first (top of stack, highlighted), then B, then A returns. The 'last in, first out' principle is labeled. A board snapshot shows the three cards on the grid with ability arrows connecting them.

Chain resolution uses a stack — the deepest triggered card resolves first.

Interrupting a Chain

A chain is interrupted if, at any point during the resolution of effects, the main zone fills up completely (all 25 cells occupied). When this happens, the game ends immediately — remaining chain effects do not resolve. Score is calculated from the current board state. See Scoring.
