When the Eldrazi Spawns die, Pitiless Plunderer triggers five times, creating five Treasure artifact tokens.
Activate the five Treasures by tapping and sacrificing them, adding ({W} magic symbol) ({U} magic symbol) ({B} magic symbol) ({R} magic symbol) ({G} magic symbol) .
Activate Najeela by paying ({W} magic symbol) ({U} magic symbol) ({B} magic symbol) ({R} magic symbol) ({G} magic symbol) , untapping all attacking creatures, giving them trample, lifelink and haste, and gaining an additional combat phase after this one.
Repeat each combat phase.
If Rapacious One has power six or greater and/or a Warrior you control can attack, this combo nets infinite creature tokens.
