At the beginning of your upkeep, discard a card, then create a Treasure token.
Mayhem (You may cast this card from your graveyard for if you discarded it this turn. Timing rules still apply.)
Ultimate Green Goblin turns your upkeep into a reliable engine: discard a card, make a Treasure, and either reanimate the discarded threat or recast it via Mayhem. You ramp aggressively with Treasures while filling your graveyard, then convert that fuel into oversized threats, reanimation, or burn to close the game. Build around the fact that discard is upside, not a cost.
Free recurring Treasure each turn ramps and fixes mana in a two-color deck
Built-in graveyard filling enables reanimator and madness/Mayhem payoffs
Mayhem lets the commander itself recur after being discarded or killed
Cheap 3-mana commander gets back on the board fast after removal
Treasures fuel sacrifice, artifact, and big-mana payoffs
Forced discard each upkeep can hurt with an empty or wrong hand
