Another card idea.
Name: Foresee (or scrying or something similar)
Effect: When this card is played, you get an additional main phase (the phase that allows you to play cards, I'm using mtg terms, sorry) after the current main phase.
My intention with this card is that you play it to see what your opponent does before you play your cards.
Or the card could wait until your opponent finishes his main phase, then show you what it is and go back to the beginning of that main phase, but with your opponent's turn locked in already. That way, initiative wouldn't have to be given up if this card is played.
This card could also be factionless.
