How it works
Move to combat.
Halana and Alena trigger, putting at least three +1/+1 counters on Cryptic Trilobite.
Attack with at least Najeela.
Najeela triggers, creating a 1/1 Warrior creature token that is tapped and attacking.
Activate Cryptic Trilobite by removing three +1/+1 counters from it, adding 6 that can only be spent to activate abilities.
Activate Najeela by paying 5, untapping all attacking creatures, giving them trample, lifelink and haste, and gaining an additional combat phase after this one.
