Big Mother Mouser

Big Mother Mouser is a slow but snowballing threat that scales very hard if it gets to attack. It starts as a 2/2, then doubles its +1/+1 counters on each attack, so it can become lethal very quickly with evasion, trample, or protection. Its biggest strength is the death trigger: even if answered, it leaves behind a pile of 1/1 Robot artifact tokens equal to its counters, so it provides strong value against removal and sacrifice effects. Best synergies are with counter doublers, proliferate, haste enablers, and ways to give it evasion or trample. Sacrifice outlets and blink/recur effects can also turn it into a repeatable token engine. It fits best in casual artifact, counter, or token decks that can protect it and maximize combat steps.
