Runebinder Iden

Whenever you activate a trap, draw a card. (Activating a trap is playing any card with trap type for a reduced cost.)

Instants, sorceries, and enchantments in your hand gain Set Trap {3} (During your turn, you may pay {3} and place this card from your hand face down as
a trap enchantment with mana value 3. You may activate a trap on a later turn to cast it for its mana value minus {3}.)
