Blizzard

When this enters the battlefield, add {e}{e}{e}
{u}: Tap target permanent
{u}{u}{e}: Destroy target nonland permanent
{2}: Target creature gains flying until end of turn
{2}: Add {e}
{x}{x}: Target creature gets -x/-x counters
{e}{e}{e}{e}{e}: Blizzard becomes a 5/5 construct
with Trample, Flying, and Indestructible, and it
gains "This creature inflicts -1/-1 counters
whenever it deals damage to creatures"
