Ashnod's Altar sacrifices Eternal Witness for two colorless, which feeds into Kenrith's 4B activated ability to reanimate her immediately; she enters, returns Time Warp to hand, and the extra turn resets the loop. Kenrith, the Returned King as commander is the anchor — he handles the recursion engine without needing a fifth piece, which keeps the line tight for any 5-color goodstuff pile.

Variations

Cheaper, tighter, alternate lines

Archaeomancer and Salvager of Secrets are direct substitutes for Eternal Witness if she gets exiled — any creature that retrieves an instant or sorcery from the graveyard on ETB closes the loop identically. For a leaner mana ask, Temur Sabertooth can bounce Eternal Witness back to hand instead of Ashnod's Altar sacrificing her, though that line needs more mana per loop and trades the Altar's colorless generation for green.
