There is an awful lot here that simply doesn`t do anything - I would be concerned that in almost every match you are basically playing with 8 cards, and 52 ways of getting those cards into play. Crop Rotation + Enlightened Tutor + Pattern of Rebirth + Defense Of The Heart = 12 cards That`s a hell of a lot of search. Too much IMHO. And what`s the white for anyway? Enlightened Tutor is just draw target Pattern Of Rebirth, and Disenchant has a better card in Green. The only card worth adding in from white to this deck is Academy Rector, while if you are playing sacrifice games (Pattern) doesn`t it make sense to partner your deck with Black? Green (25) 4 Birds Of Paradise 2 Elven Lyrist 3 Vine Trellis 1 Dawnstrider 1 Rofellos 4 Yavimaya Elder 2 Deranged Hermit 1 Rhox 4 Pattern Of Rebirth 3 Creeping Mold Black (10) 1 Boneshredder 2 Phyrexian Plaguelord 1 Fallen Angel 1 Thrashing Wumpus 3 Duress 1 Vampiric Tutor 1 Diabolic Servitude Artifact (2) 2 Masticore Land (23) 1 High Market 2 Gaea`s Cradle 2 Phyrexian Tower 2 Treetop Village 3 City Of Brass 5 Swamp 8 Forest SB could be 5 colors if you wanted - but you might need to include a basic land from that color, so you can Elder for it. I think this deck will win a lot of games with Fallen Angel/Deranged Hermit. I guess my point being that Pattern isn`t really meant to be used in these 'big green' decks - that`s what Rofellos and PoTitania are for. Pattern`s natural strengths lie in multicolored midgame flexibility, not brute force.
