Quote I know that a lot of people don't like Tempting Wurm because of its serious drawback. However, I think that this is a card that must be played situationally. It can either bust open the game for me or it takes me down screaming. It is something to combat morphling and TnT's monstosities.
Yes, but it's still bad. If you want a fat creature, Arrogant Wurm combines well with survival, or you could just run more Flametongue Kavus (it's especially good vs TnT).
Even if you keep the Wurm, it just seems that you won't have enough beatdown. Relying on 1-power creatures probably won't work, so you're left with 4 wurms, 1 uktabi, 1 FTK, and 4x rootwalla. The deck just looks like it won't be able to win quickly, and it doesn't look like it's too threatening in the late game either.
Some of the utility creatures (like the vandal) seem pretty weak. You already run Uktabi Orangutan, so why do you need worse artifact destruction? Also, why run naturalize if you can just get the creatures you need?
