Wow.
This card gives you +1 turn of stall per casting and costs you opponent any spells played (I assume that they are not returned to card form) does this rewind drawn cards?
it absolutely rewinds everything, which is why im not sure if coding would be easy
effects:
played cards return to owner´s hand after the drawn cards return to his/her deck
that includes spells.
damage to hp is undone
etc.
everything goes back in time by one turn, hence the theme of time = to the past
i would say this is an alternative to "precognition" but instead of looking at your opponent´s cards, this potentially looks through his/her strategy, giving you another chance to act differently.
