Back when Death and Taxes, and Elves, and Stoneblade were more prominent, I was also more likely to lean on Abrupt Decay as the important matches warranted instant-speed removal that couldnt be countered and didnt give my opponents a land
Liliana, Heretical Healer / Liliana, Defiant Necromancer Fine as a solo card, you can just play Liliana, Heretical Healer as a Liliana planeswalker themed commander with a nice zombie subtheme

Enter the Infinite, unlike it's affinity-based cousin is a very good card and often does read You win the game. That is what you want if you are waiting till turn 12 to do something big (although you should always protect Enter the Infinite with at least one counterspell)
