The 3 action cost would normally be steep, but it’s very doable with the assistance of other cards in this deck. The crash is worth maybe two of those actions, but the super meter gain is enormous. You have four super meters and that’s adding a gem to each, which can trigger multiple of them to go off. Play that a few times (especially if you are holding The Scepter of Power, which ALSO adds a gem to all your super meters) and you’re poised for a chain reaction of insanity that you will remember for a long time.
Puzzle Strike 2 is generally a system that creates the opportunity of miracle turns and comebacks. Dinosize pushes that so far that you might, if anything, feel overwhelmed by the power of these huge effects and the insane situations they create. Dinosized indeed!
