If an opponent would draw a card except the first one they draw in each of their draw steps, instead you create a Treasure token. (It's an artifact with ", Sacrifice this artifact: Add one mana of any color.")

This spell costs less to cast, where X is the total toughness of creatures you control.

Defender

: Until end of turn, target creature you control gets +1/+0, gains "Whenever this creature deals combat damage to a player, draw cards equal to its toughness," and can attack as though it didn't have defender.
