It's Legacy, you play w/e the eff you want. That said Enchantments isn't a great deck but it's fun to play. Thopter Sword is pretty viable.
More importantly though, Tooth and Nail is viable in Modern. So I'm running the f*** out of it. It's really, really strong aside from not having many 1 drops. Only Expedition Map in the main deck but tons of ramping 2 drops. If you cast Tooth it's the game (Emrakul + Flame-kin Zealot) but it still has other options as well.
I made the board address weaknesses. Obstinate Baloth is great loam hate and it also stares Liliana down (since aggro loam is so damn good and Raven's Crime is one of the huge keys) + general grave hate + artifact/enchant hate. I think it's pretty good vs most match-ups but I need to test more vs Jund even though that isn't the top deck anymore.
