Eh, it happens. The two ARE pretty similar.
EDIT: And, another card idea.

Randomize: Shuffle your hand into your deck, then draw as many cards as you had in your hand.
[text for Mystic Jester:]
Shuffle: Each player shuffles their hand into their deck, then draws as many cards they had in their hand.
(Notes: Obviously, plenty is open to change here -- casting cost, ability cost, stats, names... the basic idea is the ability. Clown lets you trade your hand for a random new one, while Jester does the same to both players. I chose
casting cost due to the randomness element, and
ability cost due to the draw aspect. Not sure whether a player with no hand would end up having their deck shuffled or not; it makes sense to me either way.)
