Miirym, Sentinel Wyrm + Reflections of Littjara + Ganax, Astral Hunter + Kaya, Geist Hunter

Miirym, Sentinel Wyrm

Reflections of Littjara

Ganax, Astral Hunter

Kaya, Geist Hunter

How it works

1. Activate Kaya's second loyalty ability by removing two loyalty counters from it, causing you to double any tokens you create this turn.
2. Cast Miirym either from your hand or from the command zone by paying 3 plus commander tax, if applicable.
3. Reflections of Littjara triggers, copying the Miirym spell, creating two token copies of Miirym.
4. Put all but one legendary Miirym into your graveyard due to the legend rule.
5. When the Miirym tokens enter, Ganax triggers twice, creating four Treasure tokens.
6. Resolve the original Miirym spell. Choose to put the nontoken Miirym into your graveyard due to the legend rule.
7. Each Miirym you control and Ganax trigger,
8. Resolve the Ganax trigger, creating two Treasure tokens.
9. Resolve a Miirym trigger, creating two token copies of Miirym that aren't legendary.
10. When the Miirym tokens enter, Ganax triggers, creating two Treasure tokens.
11. Repeat from step 9 for each remaining trigger, if applicable.
12. Activate a Treasure by tapping and sacrificing it, adding one mana of any color.
13. Repeat step 12 until you control no Treasures and/or you have enough mana to cast Miirym from the command zone.
14. Repeat from step 2.

This explosive dragonstorm loop begins by utilizing Kaya, Geist Hunter's -2 ability to double all incoming token creation for the turn, setting the stage for a massive cascade. When you cast Miirym, Sentinel Wyrm, Reflections of Littjara steps in to copy that spell, bringing multiple non-legendary copies crashing onto the battlefield alongside Ganax, Astral Hunter. Because every entering Dragon triggers Ganax to spawn Treasure tokens—which are subsequently doubled by Kaya's active replacement effect—you generate an overwhelming surplus of mana and artifact tokens to easily recast your commander repeatedly.
