Pals of Eternal Friendship

Flash
Choose two Legendary creatures you own from
outside the game or in exile, reveal them, and
put them onto the battlefield. They each gain
indestructible, hexproof, and protection from
black. For as long as Pals of Eternal Friendship
remains on the battlefield, control of these
creatures cannot change. If Pals of Eternal
Friendship would leave the battlefield, exile
the chosen creatures.
