When Gauss Prime enters the battlefield or attacks, destroy target creature, then tap up to two target creatures and put a stun counter on each creature tapped this way.

Redline — Whenever another creature dies put a Redline counter on Gauss Prime. At the beginning of your upkeep, if Gauss Prime has 4 or more Redline counters on him, you
may remove all of them and double his power for each stack of 4 counters until end of turn.
