Changeling
If you would draw or discard a creature card, you may choose a node:
• Draw a card for each creature that you control that is either a shapeshifter or copied creature.
• Make a copy of target artifact or enchantment a player controls, except its a changeling with power and toughness 2/2.
• Deal X damage to target player, where X is how many changelings you control.
