Flying
{t}, {1}{g}: Tornado Genie and target creature fight each other.
{x}{u}: Tornado Genie gets +0/+Y until end of turn, where Y is X + 2. Activate this ability only once each turn.
When Tornado Genie does damage to a creature, if that creature is still on the battlefield after damage has been resolved, return it to its owner's hand.
