Harmless Snail

Inevitable Doom - When Harmless Snail deals
combat damage, put X time counters on that permanent or player where X is the life total of
that player or that permanent's controller. Permanents damaged this way gain Vanishing.
Players damaged this way gain an emblem with
"At the beginning of your upkeep remove a time counter from yourself. When you remove the last counter, you lose the game."
