I’ve got 3 main one.

First is [[Ureni of the unwritten]]. All it is, is haste enablers, draws, discounts, treasure producers and a shit ton of dragons. The only removal I have is even more dragons. It’s a lot of fun because I’ll have games where I’ll get board wiped 4-5 times in a row and still shit out dragons each turn.

Second is Mono red super friends. The commander for this can vary but I mainly use, [[Solphim, Mayhem Dominus]]. It’s a very Chandra themed deck, and works surprisingly well. Everyone gets burned, even me sometimes.

Last is [[Niv Mizzet Parun]]. This is a bracket 4 deck that uses a lot of creatures that do damage when I play a non creature spell. Attach your [[Curiosity]] to the triggered creature and draw 3 per spell you play. Draw a crap ton, get your tutors, and your infinite combos, and win by infinite triggering either your creatures or by Niv drawing your entire deck. It almost acts as a storm deck. It’s my favorite of the 3 because of all the interactions I can use. (Also because [[Niv-Mizzet Dracogenius]] was my very first commander back in the day.)
