Patent
2$ Action-Duration
Reveal a card from your hand. If it is an Action, play it; if it would leave play during any cleanup, instead it doesn't.
___________________________________________________________________________
While this is in play, when another player plays a copy of the card you played with Patent, +1 Card.
If you procession a Patent, you could strand action cards in play indefinitely but wouldn't get the card bonuses. If you patent an Island, the Island doesn't get stranded in play and goes to its mat and all. Since the above the line text no longer is doing its thing it would get discarded at end of turn, just like Lighthouse gets discarded even if you want it to stay in play and provide attack immunity forever. If you patent a one-shot, same deal. If you Patent a duration card, the duration will stay in play but you won't get the effects turn after turn, because being in play has no bearing on actually getting the delayed effects, a-la-procession-wharf.
