Katara, Water Tribe's Hope

Vigilance

When Katara enters, create a 1/1 white Ally creature token.

Waterbend X: Creatures you control have base power and toughness X/X until end of turn. X can't be 0. Activate only during your turn. (While paying a waterbend cost, you can tap your artifacts and creatures to help. Each one pays for 1.)
