Really pricey card. Two readies for 4ER is nothing spectacular, and every card that cost more than 2 should be worth considering. Another reason is that you propably don't play any other card in the same turn (or play something really cheap) which means this characters must be very good or you are on the edge on win. Whatmore they must be a Avenger and Guardian character: in solo this is hard to make (because your hero can be only one of 2 characters). Multiplayer is not that muchc better. You got the alliance cost yes, but there a still tons of better alternatives. Unfortunately Cosmic Alliance requiers really focus building so it's not worth including in any random deck.

Final rating (A-C) C Only for additional challagne, or when using specific build
