You CAN Play Type I #89: It’s Official – Roland Bode Broke The Metagame!
Certainly something was broken in Growing ‘Tog, and it cannot be denied that the sheer size of its men made so many decks unplayable. If restricting Gush is your solution, though, you have to justify it due to synergy with other cards since it just isn’t that powerful on its own. (The closest analogy is Frantic Search.) The problem, however, is that you have no other alternative except for Psychatog, unless you want to ban Fastbond, which is impossible because Tolarian Academy, Memory Jar and Yawgmoth’s Bargain would have to go first… And it may well be that restricting Gush still doesn’t stop the deck.
