Resets EVE and Adonis campaigns or adds more money on one as the credits stay on them while derezzed. Can also be used during a run to stop ice destruction events from firing (Spooned, Forked, Knifed). Should work best as a one-off for resetting all your money makers in an asset heavy HB or glacier.
Correction: Timing structure is [paid abilities, rez, score] -> [turn starts]. So it would be impossible to fire the card twice. So the paragraph below is false. As it was mentioned in the comments, I'll leave it here.
You could also potentially use it to fire "at the start of your turn" effects multiple times. Early Early Premiere for example. Rez the card, use the effect, rez this, derez that card, rez it again.
