2. When the token Giant-Sized Flying Ant enters the battlefield, it and Mana Echoes trigger.
3. Resolve the Giant-Sized Flying Ant trigger, untapping Saheeli.
4. Holding priority, if you control less than four creatures that share a creature type with Giant-Sized Flying Ant, 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 Giant-Sized Flying Ant for each trigger resolved this way.
6. Activate Gemstone Array twice by paying 4, putting two charge counters on it.
7. Activate Gemstone Array twice by removing two charge counters from it, adding .
8. Repeat.
