Myojin by removing an indestructible counter from it, copying the
Eagle of Deliverance spell three times.
Resolve the first
Eagle of Deliverance spell.
When the
Eagle of Deliverance token enters the battlefield, it triggers, putting an indestructible counter on
Myojin.
Repeat from step 2.
Notes
This combo results in infinite copies of the
Eagle of Deliverance spell on the stack, which you can then resolve to put infinite indestructible counters on any creature(s) with power 3 or greater, including on
Myojin to infinitely copy any permanent spell(s) you cast in the future. If you control a creature with power 2 or less, you can put counters on it and draw cards until your library is empty.
