Jenna, the Kitten Princess

When Jenna, the Kitten Princess enters the battlefield, create two 1/1 White Cat Creature
tokens with Lifelink.
At the end of combat, if you gained 5 or more
Life, Exile Jenna, then Return her to the battlefield transformed under her owners control.
Her only bonds were to her royal pets, and they did anything to protect her in return.
