How it works
Cast Call to Glory by paying 1.
Kitsa's prowess ability triggers, giving it +1/+1 until end of turn.
Holding priority, activate any number of creatures by tapping them, adding at least 2.
Activate Kitsa's second ability by paying 2 and tapping it, copying Call to Glory.
Resolve the copy of Call to Glory, untapping all creatures you control and giving Samurais you control +1/+1 until end of turn.
Repeat from step 3.
This crafty sequence hinges on Kitsa, Otterball Elite—whose prowess ability can be triggered simply by casting Call to Glory, permanently boosting Kitsa's power to 3 so its copying ability becomes unlocked. Once that threshold is met, Call to Glory resolves its first duty by untapping your board, allowing any mana-producing creatures you tapped for resources to refresh and pay for Kitsa's copy cost. By looping this spell copy, you generate infinite untaps and infinite mana, all while Kitsa grows to staggering proportions through repeated prowess triggers alongside the combat buffs.
