Re: [Deck] Jolly Green Giant
Needs more threats, and more ways to reliably cast these threats. Honestly how fast can you cast Phyrexian Dinought?
Re: [Deck] Jolly Green Giant
Relic + Chalice seems suspect. Also you probably want a really, really good plan vs DnT since you're committing 2 crimes: being colored and legendary. The more pressing issue is that you have to have 2-3 guys already in play to even cast your 12/12 - why so desperate to play into a wrath?
There are four better things you can be doing in legacy than Ghalta: Berserk a Death's Shadow, play Dreadnought, play infect, or Entomb/Reanimate. Reality Smasher is big enough to effectively accomplish the same job Ghalta would in the stompy shell.

If you're playing bad lands than Sanctum of Ugin might be better than Mosswort, that one is at least a guaranteed giant dude with a Colossus.
