Notes
Due to differences in card templating between the various banisher effects (linked triggered abilities vs "until" clause), steps 3, 5, and 7 may return the creature to the battlefield during the resolution of the preceding step rather than creating a separate event. This should not affect the overall execution of the combo, only how many objects pass through the stack (and thus rounds of priority available per loop).
Results
Infinite creature ETB.
Infinite creature LTB.
Infinite blinking of permanents.
Infinite mana lands you control can produce.
