I'd suggest Pawn of Ulamog, that way you can pretty much sac each creature twice because of the spawn it makes.
What's the point of Spikeshot Elder? You don't have any cards that can boost it except Teetering Peaks, which it still wouldn't be worth it.
With all those artifacts you might as well replace Flame Slash with Galvanic Blast.
Yea, and maybe with Lotus Cobra. I figured that misty rainforest could replace a forest as it provides no disadvantages because the land doesn't come in tapped.
