Oversoul
The Tentacled One
So that first game after making my changes was pretty lousy, but I finally played a second. It was much better. Right when the other players had built up formidable board states, Zirilan was able to fetch Drakuseth on the end step before my turn and Balefire Dragon in my upkeep, getting rid of opposing creatures. Sacrificed both dragons to Phyrexian Altar for mana to cast Siege Dragon. My opponents worked to rebuild their boards, so I set up mean play. I felt a little bit bad, but I did put it in the deck so it's not like I wasn't going to use it. Floating eight red mana, I fetched Worldgorger Dragon from my library with Zirilan's ability. Once my stuff was exiled, I used my remaining mana to cast Apocalypse. Opponents lost all their permanents and I got mine back. They conceded rather than waiting another couple turns for me to finish them off in that situation.
