Goon Battery (Blue)

Goon Battery’s ability generates a conditional continuous effect that is always checking. If you control less than 3 auras when you attack with this, then you control 3 or more auras, this will get +3 and gain the “when this hits a hero” triggered ability.

Goon Battery’s ability is not functional while defending.

If you gain control of a third aura during the damage step and it causes the if-conditional effect to become active, it will get the +3 from controlling three auras but the damage will not be recalculated.

The triggered ability gained from Goon Battery’s ability triggers when it hits a hero. You will tap that hero when the triggered effect resolves.

If the number of auras you control becomes 2 or less while the triggered effect is waiting to resolve on the stack, you will still resolve the triggered effect and it is not removed from the stack.
