My biggest issue is that this promotes the style of play I just don't like. The game is already, "Can I activate out before my opponent can mitigate." This makes it more so. It's not only a great card in it's own right, but it's also great with every other action advantage card. Played with Rey, Tactical Mastery, Jango, All In or any other action accelerator, now you not only get to resolve your dice before an opponent can mitigate, you can also mitigate their dice in the same window. Not hard, considering it costs zero to play. I'd have considered this auto-include in blue decks even if it costed two resources. Zero is just stupid unless there's a better version of Confiscation coming that we don't know about.
Awakenings printed entirely too many control cards that mitigation decks made the game less fun than it should have been. Players responded by warping the meta into action advantage decks. Now they're just feeding those, which are also less fun to play against than the game should be. The action/reaction component of the game is it's backbone and they're pushing it out.
