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 Stonework Packbeast twice by paying 4, adding .
7. Repeat.
