Winter's Famine

At the beginning of your upkeep, put a snow
counter on Winter's Famine. Then each player
taps a creature they control for each snow
counter on Winter's Famine.
Creatures don't untap on their controller's
untap step.
{5}: Until your next turn, Winter's Famine loses
all abilities. Put a snow counter on Winter's
Famine. Any player may activate this ability.
