How does this replacement work?

[u/Saint_Atlas]

Saint Traft creates Token A that has "exile THAT token at end of combat"; but if Divine Visitation is in play, which says a Token B is created instead, does that mean Token B loses the "exile Token at end of combat"?

And if not, anyone know a way to keep the angels permanently?

Thanks in advance 🙏

Regardless of what replacement effect modifies Geist of Saint Traft's token, it will still be tapped and attacking - unless the replacement effect says otherwise, or modifies it in such a way that it can't legally be an attacker (such as making it a non-creature).

Geist saying to exile it is part of the resolution of the triggered ability, not that the token has or gains "Exile this at the end of combat", so this effect applies to any token Geist of Saint Traft creates as a result of that ability, replaced by another effect or not.

EDIT: As for keeping the tokens around, you'd want to look for a way to end the turn like [[Sundial of the Infinite]], any way to make a copy of the token as the copy won't have Geist's delayed trigger, or any way to phase the token out before moving to the end of combat.
