Legends Passed Down, Zeus

Play this with [COST][Counter-Blast]1] if you have a vanguard with "Zeus" in its card name! Choose one of your vanguards, until end of turn, it gets [Critical] +1, and all of your front row units get [Power] 10000. Choose a card from your hand, and you may discard it. If you did not discard, choose two face up cards in your damage zone, and turn them face down.
