Cataclysm in a slightly worse discard zoo shell.

It is actually really good with 3+ "discard me" cards in hand as a board clear + some combination of 3/3s, burst damage and draw.

Do not save your malchezaar's imps for turn 5 imp + cataclysm, they are better early as a 1/3 plus 1~2 cards.

Always mulligan away direct damage cards and felwing.
