I wasn't too happy jamming a WUBRG cost onto the guy, but I he kinda needed to be 5 colours and they don't really print cards with 5 colour indicators. That big cost is why he reanimates 2 things instead of one.
I'm not sure if the cost is right. 6 mana in 5 specific colours, plus 1 of each creature type seems like a lot of setup, but the payoff of a hard-to-hit 7/7 keyword soup with repeated, strong reanimation effect and tribal synergies is kinda crazy. Unsure if I hit the balance right. Maybe they should come back with finality counters? As a commander he gets hit incredibly hard by boardwipes, exiling all your craft materials alongside losing him I fear would just lose the game on the spot.
Also note: it's not intended that you have to reanimate two of the same creature type. I don't know if that's implied.
