Steps
- Declare the creature that has Infantry Shield attached as an attacker, triggering its ability, creating a number of 1/1 Warrior creature tokens that are tapped and attacking equal to the creature's power.
- Holding priority, activate Phyrexian Altar five times by sacrificing five Warriors, adding {W}{U}{B}{R}{G}.
- Activate Najeela by paying {W}{U}{B}{R}{G}, untapping all attacking creatures, giving them trample, lifelink and haste, and gaining an additional combat phase after this one.
- Repeat.
