Whenever Green Goblin attacks, discard a card. Then draw a card for each card you've discarded this turn.
Suit up Green Goblin and swing in the air with deathtouch, churning your graveyard while refilling your hand each combat. You leverage the discards as setup for madness, reanimation, and graveyard payoffs, then convert raw card advantage into a grindy aggro-reanimator finish. Stack additional discard outlets and the attack trigger snowballs into multiple cards per turn.
Built-in repeatable card advantage and graveyard filling every attack
Flying + deathtouch makes a 5-mana evasive blocker deterrent and consistent damage source
Enables madness, reanimation, and discard-matters payoffs for free
Strong in grindy attrition matchups where raw card flow wins
Needs to attack to generate value, so removal/board wipes blunt the engine
Color identity lacks easy enchantment/artifact answers
Without discard payoffs the loot is purely fair card draw
Vulnerable to graveyard hate shutting off reanimation synergies
Self-discard can pitch bombs randomly without selection support
