Bug Report: Primordial Altar

"Once during each player’s turn, that player may look at the top card of their deck. They may discard that card."

Opponent played primordial altar. I used it twice, chose not to discard, then received a different card than revealed upon next draw. They were supposed to be rare candy and energy recycler, instead I received other cards that were much less helpful at the time. Either it was showing the wrong card or changing my next draw from what it should be, frustrating either way.
