Greta Loewen

When Greta Loewen enters the battlefield, create a 2/2 Legendary Creature Horse named Cheryl and a 2/2 Legendary Creature Horse named Ruth.
Horse tokens you control can phase out just like nontoken creatures.
If a blocking creature you control would die, you may pay X where X is the mana value of that creature. If you do, that creature phases out instead.
