I wasn't looking at it from the perspective of a rotating dealer game. It is possible for the dealer to cheat in a manner of speaking but it depends on how they shuffle the deck.
If you use the riffle shuffle, you can peek at both bottom cards when you go to split the deck halves into both hands. If you table riffle, like you see in casinos
you can peek at the bottom few cards before your last shuffle. With practice, no one will be able to catch the peek or suspect it even happened because you'll do it so quick.
Once you've got two or three cards memorized, cut the deck but cut it a bit past 50% of the deck, maybe around 60% (assuming 8 or 9 players. Go even deeper with fewer players). This will put the memorized cards slightly above the halfway point of the deck and if you cut the deck properly, should ensure that both memorized cards end up on the board or at the very least (if you didn't cut too deep), stay with the deck stub.
Now don't assume I advocate cheating; I am just stating how someone who is dealing can easily cheat IF THEY WANTED TO. At the very least, keep an eye out for when someone else is dealing. I'd even recommend someone else to cut the deck after the dealer has shuffled it.
