Mother Says

Upkeep: add an age counter to this card.
Then, roll 1d6
1-2, you sacrifice a creature.
3-4 each other player sacrifices a creature.
5-6 each player sacrifices a creature.
If there is only 1 creature in play at your upkeep, sacrifices this card, add x +1/+1 counters to that creature (x is equal to the number of age counters
on this card.)
