The Empty Child

At the beginning of your upkeep you lose 1 life.
{t}: Put a gas-mask counter on target creature.
As long as the creature has a gas-mask counter
on it, it is 1/1 and has "At the beginning of your
upkeep you lose 1 life."
When The Empty Child leaves the battlefield,
remove all gas-mask counters.
Are you my mummy?
