Drop {zephyr charge} use it to give the opponents creatures flying, than play a card that destroys a creature/creatures with flying
Ah this is a stupid idea. Never mind
You would have to {isocron septor} a {plummet}
{tropical storm}
{wind storm}
{hurricane}
{crushing vines}
{arial predation}
{eaten by spiders}
Oh hey, {Gruul Charm}...
