Mecha'thun Rouge (The Boomsday Project) Classic

This Mecha'Thun Rogue deck uses loads of tools to quickly mill your deck and activate Mecha'Thun.

To activate the Mecha'Thun you need to have used your hero power the turn before and have only Mecha'Thun, Doomerang, Evenom, Preparation and either a coin or another preparation. You make your weapon poisonous, throw it at your Mecha'Thun and win.

This seems like the type of deck Disguised Toast would use...
