Whirlwind, Tempest Dragon

First Strike, Flying

When Whirlwind enters, return each other nonland permanent with mana value less than X to its owner's hand, where X is the amount of life you gained this turn.

If you would gain life, choose one of the following instead:
• Whirlwind deals that much damage to target creature an opponent controls.
• Distribute that many +1/+1 counters among creatures you control.
