This is a totally cool trick that I found while looking at some of my cards.
Get 2 Jungle Mankey and a Rocket Rattata on your bench, use peek on the top
card of your deck and one of your prizes, if you need the card in your prizes
that you peeked at, just use Rocket Rattata's trickery to switch it with the
top card of your deck. On your next turn, you'll get the card that was one of
your prizes. It can be really useful and in some situations it can save you
the game.
