Is this cheating or am I missing an exploit?

Serious question, because I was impressed.

If it mattets, Im Pro rank but generally play meme decks.(especially lately) no judgment,.its Just how I roll.

But just now I encountered a Nilfgaard deck that managed to play 2 Renfris in succession on rnd 2, without having the prior renfri in their graveyard (or mine), or stealing one from me.
How?
Thanks.

edit
TBH I don't think it's really a cheat, but I hadn't seen this exploit before or how it was done, and I reeeeeallly want to know how.
The last card before the magic happened was Canterella, but I had a Renfri in hand with a NR cursed 25 (I was playing my "hot garbage" deck)

Edit bad thumb typing typos

Edit edit Thank you throwaway854 account, the way it was done was with land of 1000fables that managed to spawn them a Renfri.
