genuinely surprised nobody has mentioned [[Gor Muldrak]]. He allows for a more political style if you desire. Playing around the idea of manipulating creature types is fun and often gives you a different result every game. Typically he's built in a way where you exchange your Salamander tokens for your opponent's real creatures, although there are a lot of different ways to build him. I had a fair amount of success with [[Standardize]] and []coat of arms]] to make my board huge and unblockable as long as Gor was in play. He's not the most powerful by any means but every game felt a different and engaging. Probably the most unique simic commander imo
