Tristan's First Flight

Tristan's First Flight deals damage equal to twice
the total power of up to three target white
creatures you control to target creature an
opponent controls.
That creature loses Indestructible this turn.
Then the three creatures you control each gain
First Strike, Flying, Lifelink and Trample, and
get +X/+0 until end of turn, where X is the
highest power amongst the three creatures.
