Buzzsaw Trap (Blue)

“When this defends” is an event-based trigger. The power of the attack is checked at the time this resolves and becomes a defending card (i.e. defends the attack). If the trigger condition is met only after this resolves, then this does not trigger.

Any effect that increases the power of an attack is retroactively and proactively prevented by this triggered effect (e.g. gets, gains, has etc.). This typically makes the modified power of an attack equal to its base power.

Counters that increase power are also prevented from modifying power by Buzzsaw Trap.
