What Can I say but HOLY AWEsome. Unchanged from it's previous incarnation except in name.
Shield trigger of "time for Payback". Taps all opponents creatures, ok how much more awesome do we need to get folks.
Strategies and game play:
If used as a shield trigger great for stopping that mass kill scenarios, If used as a spell great for causing mass destruction. Can be used in any deck Even if they are the Only 3 Light cards in it.
Combos with other cards:
Combo? combo? combo? well other than tapping up your opponent to let you attack his creatures or shields freely what more needs to be said?
Ways to counteract it:
having a Current Charger creature, or having used a Regroup spell before you attack. These will untap your creatures at round end to keep them from being targets, and you from being completely open.
Cost 6 spell trigger of awesomeness.
Cost 6 spell trigger of awesomeness. That and if hit early id does not need to be used and can become intsa-mana next turn.
none yet, but in old games there were cards that tapped all creatures that were not light.
Artwork and aesthetics:
I miss my Old Holo Raichu version from tournament play.
Giving this card a 9.5, can be argued as the strongest of all shield blast cards. Yes, Terror Pit and Root Trap remove a creature, BUT it is only one creature.
