#### Card cap

Applies to the sum of every card on the Table with the same effect, before family combos and sets.

- Attacker losses: 12% · above 7.2%, each point counts 50%

#### Effect by star

Each star multiplies the card’s effect and cost: 1★ ×1, 2★ ×1.25, 3★ ×1.5, 4★ ×1.75, 5★ ×2. Shadow combos reduce the cost, and some sets cancel it.

| Star | Effect | Declared cost |
|---|---|---|
| 1★ | −6% losses when attacking | +6% losses when defending |
| 2★ | −7.5% losses when attacking | +7.5% losses when defending |
| 3★ | −9% losses when attacking | +9% losses when defending |
| 4★ | −10.5% losses when attacking | +10.5% losses when defending |
| 5★ | −12% losses when attacking | +12% losses when defending |
