(T: Add B.)

Changeling (This card is every creature type.) As Morophon enters, choose a creature type. Spells of the chosen type you cast cost WUBRG less to cast. This effect reduces only the amount of colored mana you pay. Other creatures you control of the chosen type get +1/+1.

Whenever a creature you control enters, you gain 1 life. If this enchantment isn't a creature, it becomes a 3/3 Angel creature with flying in addition to its other types until end of turn.

Whenever you cycle this card or cycle another card while this enchantment is on the battlefield, you may exile target creature. If you do, return that card to the battlefield under its owner's control at the beginning of the next end step. Cycling 2W (2W, Discard this card: Draw a card.)

Create two 1/1 white Bird creature tokens with flying. Flashback—Tap three untapped white creatures you control. (You may cast this card from your graveyard for its flashback cost. Then exile it.)

Kicker 2U (You may pay an additional 2U as you cast this spell.) Destroy target artifact or enchantment. If this spell was kicked, draw two cards.

Outlast 2 (2, T: Put a +1/+1 counter on this creature. Outlast only as a sorcery.) Other Sliver creatures you control have outlast 2.

Exile target creature you control, then return it to the battlefield under its owner's control. Rebound (If you cast this spell from your hand, exile it as it resolves. At the beginning of your next upkeep, you may cast this card from exile without paying its mana cost.)
