Mono-Black Zombies and Dimir Zombies are going to be just as big in standard as werewolves.
There is a huge support for the zombie tribe, and Champion of the Perished will be at the forefront of all those lists.
Play this, then Wight, and Rotting Regisaur, and you'll end up with 13 points of attack power on turn three. The best part about this card is that it just keeps growing with each turn. This means that opponents will have to go an extra mile to remove it as soon as possible.
