Oversoul
The Tentacled One
So I guess I wanted to use all the old spike creatures, but Spike Cannibal doesn't play nicely with the others, so I went Selesnya and figured Lathiel would be perfect. Then because a unicorn's horn is kind of like a spike and the deck would have spikes, I branched it out to be themed around various spikes, horns, and tusks. Also lifegain. So yeah, this is weird. But whatever. I think it'll work. Maybe I'll post an update here if it does or even if it doesn't.
