Ender Dragon

Flying.
When Ender Dragon enters the battlefield,
choose any number of the following:
•Eye of Ender (Target player reveals their hand)
•End Portal (Exile target creature)
•Ender Pearl (Target player gets an emblem stating: "Whenever a source deals damage to you, deal that
amount of damage to its controller.")
If Ender Dragon would die, shuffle it into its
owner's library instead.
