Liliana of the Veil Liliana of the Veil was a former best planeswalker of all time, and proved its worth for over a decade
Im planning to do a lot of digging and drawing cards with Rumor Gatherer in my Adeline, Resplendent Cathar deck, where I can reliably trigger her ability at least three times on each of my turns
There are comboing Dragons, Vampires with incredible protection, and Merfolk that accrue so much card advantage that it can be staggering
Griselbrand As one of the best card draw effects in black, not to mention a massive flying threat, Griselbrand is probably the most-played demon in MTGs history, despite being banned in EDH
However, with four players at a normal Commander table, it should be reasonably simple to commit a crime each turn, allowing you to untap six new Zombie Mercenaries on your next turn
