I might build this one too, because I could the roll a die for odds or evens! Obosh has the similar neat restriction fro edh that breaks monotony while offering a one sided furnace of rath. Out of all the options, this one mas the most viable commanders to pair with. I have many options in rakdos, jund, mardu, and grixis. I have huge hasted beaters that hitting for double damage would be lethal and persistent damage options. I have a grixis partner option that would give me a three some (wild)! Obosh and the Plague have great synergy and flavor and are in a color combo of mardu which I don't explore often. My other favorite is Darigaaz as I thought it was always cool and if they kill it he comes back on his own. He also would a neat twist from being Nicol Bolas. If we are in green, the land chucking cards are all accessible to us, turning lands into fireblasts is bananas. No matter what version I choose, it's sure to be goblin heavy! Pashilik mons, goblin grenade, goblin sharpshooter, and voracious dragon are just too fun and super excellent with Obosh. I think this deck is going to focused on hitting heavy and fast and less about artistry. Smash baby!
