Flying Whenever this creature deals combat damage to a player, it deals that much damage to each creature that player controls.

Changeling (This card is every creature type.) As this creature enters, choose a creature type. Whenever another creature you control of the chosen type enters, put a +1/+1 counter on this creature.

When this creature enters, create X Treasure tokens, where X is the number of artifacts and enchantments your opponents control. (Treasure tokens are artifacts with "{T}, Sacrifice this token: Add one mana of any color.")

Flying Whenever another nontoken Dragon you control enters, create a 5/5 red Dragon creature token with flying. {1}{R}: Dragons you control get +1/+0 until end of turn.

As this creature enters, choose a creature type. This creature is the chosen type in addition to its other types. Each other creature you control of the chosen type enters with an additional +1/+1 counter on it.

As an additional cost to cast this spell, discard a card. Draw two cards and create two Treasure tokens. (They're artifacts with "{T}, Sacrifice this token: Add one mana of any color.")
