Actually Cleafairy Doll would actually be much more useful.
The format is currently extremely fast and if you can't get setup by T3 you could very well be in for a blood bath.
Giving up an early prize can mean the game, but Clefairy Doll COULD BE slightly useful with decks that take a little longer to setup.
Seriously, if the doll gave up prizes...
what would be the point of its existence?
Then it would be easier to use Scramble .
