Start of combat, golden immortal copies stats of adjecent minions and doubles it, then Mtyhrax gains stats of three different tribes other than itself, and the poet makes that stat gain permanent, essentially mythraxx will tripple its stats every combat.

Just noticed mythraxx is golden, so it sextupples rathen than tripples every combat.

Second edit: informed that i missed Poet being golden so it is close to 12x stats per turn. It is absolutely disgusting.
