It is apparent that the card needs some reworking and despite the fact that I would really rather leave the theme of Time Slip as is, if at least with an increase in cost, I'll make 2 versions and see which gets more votes.
EDIT: Poll up, please vote. The first version is a more restricted version of the original card, allowing only 2 copies of target card to be drawn from the deck. The second version is a slightly inverted take on the original Time Slip not allowing for card drawing, but allowing a player to be able to play whichever card at a whim, at the cost of delaying all of his/her creatures.
