Obviously it has been discussed a lot, but I’m going with the Mecha’thun+2x galvanizer combo and bloodbloom to cast cataclysm. Hemet works well in this deck to thin it out, and everything that costs 4 or more is pretty relevant in play. I could certainly see going even “quicker”, cutting out maybe hooked reavers in hopes for 2 mana card draw like bloodmage or loot hoarder. Definitely an option I’m looking into.
