Pressurebuster

Program: +2/+1 (Programmable Bots you control get +2/+1)
Whenever Guardsquad Pressurebuster attacks, flip a coin. If you win the flip, put a smog counter on target creature, then deal 1 damage to it. If you loose the flip, put a smog counter on target creature you control, then deal 1 damage to it.
Whenever a creature with a smog counter on it is dealt nocombat damage by a source, that source deals double the damage instead.
