Legendary Creature — Human Scientist Villain // Legendary Creature — Goblin Human Villain

Norman Osborn
Norman Osborn can't be blocked.
Whenever Norman Osborn deals combat damage to a player, he connives. (Draw a card, then discard a card. If you discarded a nonland card, put a +1/+1 counter on this creature.)
: Transform Norman Osborn. Activate only as a sorcery.

Green Goblin
Flying, menace
Spells you cast from your graveyard cost less to cast.
Goblin Formula — Each nonland card in your graveyard has mayhem. The mayhem cost is equal to its mana cost. (You may cast a card from your graveyard for its mayhem cost if you discarded it this turn. Timing rules still apply.)
