Both Titans seem very powerful, however [Card]Uro, Titan of Natures Wrath[/Card] takes the cake for me
It lets you cast creatures directly from the graveyard by exiling other cards, making it perfect with self-mill spells like Grisly Salvage or Satyr Wayfinder
It also means, if you decide to go with three colors, that white, black, and green (called Abzan) is a good possible option
The free tier covers deck building with mana base math, collection tracking for up to 10,000 cards, and set completion
By the numbers: What BOTH Disfigure and Fatal Push kill without revolt .: 64 (examples: Grim Lavamancer, Lotus Cobra) What BOTH Disfigure and Fatal Push kill with revolt: 33 (examples: Oracle of Mul Daya, Goblin Rabblemaster) What Disfigure kills and what Fatal Push can't, even with revolt : 3 (Shriekmaw, Kiki-Jiki, Mirror Breaker, Mulldrifter, Acidic Slime) all of these being Mulldrifters whose main value comes outside of the creature itself
