FAQs/Rulings
If my next attack after resolving this effect is not with this card, will I lose this effect?
No. It applies to the next Mono Ally you attack with in the Round once the effect is resolved. That attack can come any time after the effect resolves as long as it is still within the same Round.
What does "Double Defended" mean?
It means a card must be defended by either 2 matching or 2 non-matching Allies.
