Bryn, Princess of The Scorch

When Bryn, Princess of The Scorch enters the battlefield, summon Kalix The Scorch Dragon to the field from your deck, hand or graveyard.
Shuffle your deck if Kalix The Scorch Dragon is summoned from the deck.
At your end-step if you control both Bryn, Princess of the Scorch and Kalix The Scorch Dragon exile them, then meld them into Bryn, Scorch Heiress.
