You control at least three Dwarves that don't have summoning sickness and that cannot be blocked by an opponent.
Steps
Deal combat damage using three Dwarves.
Thorin's first ability triggers three times, creating six Treasure tokens.
Holding priority, activate 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 lifelink, trample and haste, and causing you to get an additional combat phase after this one.

Najeela will also create infinite Warriors that will then gain haste from its ability.
