One of my favorite commander decks is 5 color mutate. It's tons of fun and generally underrated. Commander can either be [[ramos dragon engine]], or [[cromat]]. Recently me and my partner have also been working on baldurs gate background commander decks with the anticipation of BG3 coming out. We just finished up [[Karlach, fury of Avernus]] + [[Guild Artisan]] for a mono red multiple combat + treasures deck.
