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

Waterbend : 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 .)

If a triggered ability of an Ally you control triggers, that ability triggers an additional time.
