Assuming that you are only running 3 of your main attacker, it becomes relatively easy to work around. You don't have any way to quickly get these things up, so once a couple go down you are crippled. Most decks are going to have a way to revenge kill this thing, in some way shape or form. So you take a prize, then it is revenged, and you have to keep repeating this process, whilst also attaching two energies and getting multiple stage twos out, all while under trainer lock. That is assuming that you actually successfully start the game, which is somewhat unlikely in this format what with all of the easy ways to just drag and drop whatever happens to be laying around on the bench.
It's like 90% of other cards that have looked amazing on paper before, sure it'd be great but it is never as good as you'd think. Also I enjoy the OP relating statistics back to Video Game hit percentages, just gave me something to smile at.
