Saheeli, the Sun's Brilliance + Mana Echoes + Gemstone Array + Glamermite

Saheeli, the Sun's Brilliance

Mana Echoes

Gemstone Array

Glamermite

How it works

1. Activate Saheeli by paying and tapping it, creating a token copy of Glamermite with haste.
2. When the token Glamermite enters the battlefield, it and Mana Echoes trigger.
3. Resolve the Glamermite trigger, untapping Saheeli.
4. Holding priority, if you control less than four creatures that share a creature type with Glamermite, repeat steps 1 through 3 one additional time.
5. Resolve all Mana Echoes triggers, adding C for each creature you control that shares a creature type with Glamermite for each trigger resolved this way.
6. Activate Gemstone Array's first ability twice by paying 4, putting two charge counters on it.
7. Activate Gemstone Array's second ability twice by removing two charge counters from it, adding .
8. Repeat.
