15) (mancer / wall) + pan + (displace / ghostly flicker) + (warp / manipulation) = infinite turns

1) aminatou + (felidar guardian / spark double) + altar of the brood || blink loop with altar on the board mills everyone out (better with leyline of the void)

2) aminatou + felidar guardian + (corpse knight / ayara / vela) || blink loop with knight or ayara on the board is infinite life drain

3) (aminatou / ghostly flicker / displace) + lumbering battlement + (felidar guardian / restoration angel) + (ETB or LTB creature) ||  tuck felidar and last combo piece under battlement and blink it. stack is: felidar on battlement on last piece is infinite ETB triggers.

4) aminatou + parallax wave + felidar guardian + (ETB / LTB creature) ||  tuck felidar and last combo piece under parallax and blink it. stack is: felidar on parallax on last piece is infinite ETB triggers.

5) aminatou + (panharmonicon / oath of teferi) + felidar guardian || blink a land infinite times for infinite mana (or infinite life loss with piranha marsh or sunscored)

6) aminatou + (panharmonicon / oath of teferi) + felidar guardian + any LTB /ETB perm or land||

7) (displace / ghostly flicker) + (archaeomancer / mnemonic wall) + peregrine drake + land || infinite mana. add scrib nib for all libraries exiled or specifically desert or marsh for inf damage

8) (displace / ghostly flicker) + (archaeomancer / mnemonic wall) + panharmonicon + any instant or sorcery from hand or graveyard = infinite recasts

9) 10) 11) panharmonicon + (felidar / resto) + spark double || play spark as a copy of felidar or resto, blink it and something else (creature if resto, anything else if felidar, including land for infinite mana)

12) parallax wave + felidar + peregrine drake || cast felidar with drake and wave on the battlefield, targeting wave, and with that on the stack, exile both with the wave. felidar then blinks the wave so all 3 permanents return. untap 5 lands with drake, tap for 5 mana, target the wave with felidar, exile the 2 again, repeat for infinite mana

13) deadeye + peregrine || infinite mana

14 (archaeomancer / mnemonic wall) + (thassa deep / conjurer's closet) + (time warp / temporal manipulation) || cast time warp with mancer or wall on the b, EoT blink mancer or wall to recur it for next turn.

14 (archaeomancer / mnemonic wall) + panharmonicon + (displace / ghostly flicker) + (time warp / temporal manipulation) || cast time warp with mancer or wall on the b, this turn or next, ghostly flicker mancer or wall with pan on the b, flicker resolves, so you can target the time walk and flicker.
