Kalamax, World Ender (EDH / Commander)

Kalamax the Stormsire

Power Level 7/10 Kalamax helms a combo deck capable of taking people out of the game within a few turns, or flat out winning. This is backed up by powerful card draw and the ability to copy spells to create a single massive follower. However the deck is held back by suboptimal cards.
Speed 10/10 Possible turn 3 wins and the ability to win out of nowhere allow the deck to pressure it's opponents easily.
Consistency 7/10 The deck can draw more cards than it knows what to do with, it might have only a few copies of key cards but that doesn't matter with the sheer amount of value it can generate while building board presence and managing other players boards.
Resiliency 8/10 So long as the deck has a full hand it can come back from any setback, so long as you mulligan properly this isn't difficult to achieve.
Defenses 4/10 The deck is overly reliant on Kalamax, however it also has a bunch of ways to protect him so the score isn't too low.
Complexity 9/10 The deck is not purely built around the combo, it is a value deck as well. Properly ordering plays will come up during each turn cycle, and will either make or break the game for you. As such it is a fairly complex deck to play in most games.
