You could go ahead and play it at FNM for fun, but I don't think you'll win much. I would probably take out Bond Beetle, Chronomaton, Unexpected Results, and Leyline Phantom in favor of better stuff, like more of Zameck Guildmage or Fathom Mage, or Rapid Hybridization . Master Biomancer is pretty good, if you could manage to get it.
You know what this deck needs?
It's not easy to make a deck that comes straight out of a intro deck. Keeping a deck under $50 is nearly impossible now, and you've made one...this is a great job. Keep up the good work!
Just as proof that this deck works. I went to my first FNM yesterday and went 2-2. Not bad for a newbie huh?
Again, creatures with counter play ---> Hindervines
Having trouble with aggro? ---> Timberland Guide
Crocanura - 2G for 1/3 Evolve Reach
Pros: Low/mid cost
Cons: Evolve is bad for this. Reach needs higher power. Reach (Should besideboard), 1/3
Cons VS DBG: DBG=5/5 for 1 more mana + Scavenge to pump
Adaptive Snapjaw - 4G for 6/2 Evolve
Pros: Big head, Toughness Evolve
Cons: Cost, low starting toughness, focused.
Cons VS DBG: DBG is one less cost for 5/5 + Scavenge to pump
Deadbridge Goliath - 2GG for 5/5 Scavenge x5 1/1 counters
Pros: Mid range cost for 5/5, super huge scavenge, clutch play
Cons: Focused (Not always a con, scavenge)
Cons VS Crocanura : No evolve, No Reach
Cons VS Adaptive Snapjaw : No evolve
and once you make your creatures huge, they need to trample Rancor
24 lands is perfectly acceptable.
Why not go Bant? The colour combination affords you card:Avacyn's Pilgrim which, in tandem with Arbor Elf , would let you jump the cut from 1 cmc straight to 3 cmc spells by turn 2. It's a viable idea seeing as in UW you've got Lyev Skyknight while in GW you get Loxodon Smiter AND Centaur Healer all three of which are more likely to trigger your evolve triggers with that 3+ power/toughness which means dropping a turn 2 Elusive Krasis is definitely going to be something your opponents REALLY should be wary of.Another situation this affords you is a turn 3 Experiment One followed by a Strangleroot Geist , which really gives you 3 triggers off that evolve trigger... letting you swing in for 4, 2 of which is unblockable, while the other 2 the opponent will probably let through if they don't want evolve to trigger again.
Updated with cards I own. Thank you all for the advice I really appreciate it and when I come into some money I will definitely be buying those cards to power my deck up
