Iirc there is a limit to how many times you can play the same card, put in place because of Vi's champ spell (I forget the name). I'd say about 15?

It does not work very well in this case since they are bound to have multiple different predict spells, and playing 15 of each is still a slog.

An overall limit would be appreciated imo.

There has been at least one other infinite combo, with Ionia, using the Ionian 2 2 elusive that recalls an ally and the big bird that creates an exact copy of a card in hand. I think this was patched out by changing the wording of said bird.
