Kirol, Attentive First-Year + Meneldor, Swift Savior + Sunstrike Legionnaire

Kirol, Attentive First-Year

Meneldor, Swift Savior

Sunstrike Legionnaire

How it works

1. Deal combat damage using Meneldor, triggering its ability.
2. Holding priority, activate Kirol by tapping it and Sunstrike Legionnaire. copying Meneldor's trigger, targeting Kirol.
3. Resolve the copy of Meneldor's trigger, blinking Kirol.
4. When Kirol enters, Sunstrike Legionnaire triggers, untapping Sunstrike Legionnaire.
5. Repeat from step 2.

This clever loop centers around duplicating Meneldor, Swift Savior's combat damage trigger with Kirol, Attentive First-Year's tap ability, using Kirol and Sunstrike Legionnaire as the required tap cost. Because Kirol is exiled and immediately returned to the battlefield by the copied trigger, it resets its once-per-turn activation constraint and causes Sunstrike Legionnaire to untap via its own creature-entry trigger. This elegant interplay generates infinite creature enters-the-battlefield and leaves-the-battlefield triggers, all fueled by the repetition of blinking Kirol back to safety.
