When you think Fate to 1 would destroy the deck, then you have no clue how OP the deck is. It doesn't need fate to rule. And even with fate at 1, it would be useable up to 5 times.
I feel like the ideal Sylvan hit would be Rose Lover and Marshalleaf both being semi-limited. They're really the two OTK enablers, and having to choose between them would solve a lot of problems. (Also has the side-benefit of not hurting non-Sylvan Plant decks much, which isn't SUPER-important, but worth mentioning.) I kinda wish Carrot wasn't a card, too, but it's probably not banworthy.
That show that you have no clue what combo is behind fate.
There's a monster, that bansih 3 SB cards from grave to SS itself. So you can get fate up to 4 times with eternity.
There's a monster, that put back a SB card from your grave each turn. So even when it get removed the next turn, it mean also +3 fate.
But yeah no brain just complaining?
