6. Activate Jhoira's Timebug by tapping it, putting a time counter on Idris.
7. Move to your extra turn.
8. At the beginning of your upkeep, Idris's vanishing ability triggers, removing a time counter from it.

10. Idris triggers, causing you to take an extra turn after this one.
11. Repeat from step 6.
