Graft is an Event that lets you create your own split piles! When you buy it, you get a choice of taking the top half of one Kingdom pile and putting it on top of another (e.g. I take 5 Villages from the Village pile and put them on top of the 10 Markets), or rotating any Kingdom pile, similar to Battle Plan. I restricted it to Kingdom piles to prevent obnoxious things like putting 23 Coppers on top of the Provinces, etc. Players can use Graft sort of like Tax or Embargo to put a stack of bad cards on top of ones their opponent might want, but it also allows for some interesting pile control, adding more cards to low piles or halving a pile to threaten a pileout. It also always feels good to buy a card then rotate the pile away from your opponent.
FAQ:
-A Kingdom pile is any pile in the Supply that is not a Basic card (Copper, Silver, Gold, Estate, Duchy, Province, Curse, Platinum, Potion, Ruins, etc.). You may not take from Basic cards or put other cards on top of these with Graft.
-If a pile has an odd number of cards, round down the number you take off the top (e.g. take the top 4 cards from a 9 card pile). You may not use Graft to take from a pile that has 1 card left.
-Always take half of the pile, even if there's cards from multiple piles (e.g. if you Graft from a pile of 7 Villages on the bottom and 5 Moats on top, you would take 5 Moats and 1 Village to put on another pile). You may not reorder the pile you take from or the pile you place on.
-Graft uses similar rules to official split piles--you can turn the bottom cards sideways to indicate multiple cards in the pile. Players may look through the pile (the one exception is Knights--if Grafting Knights, count the pile without looking at the cards below the top one).
-You may place cards onto an empty Kingdom pile.
-You may only buy/gain the top card of a Supply pile. When a card instructs you to gain a copy of a card (like Talisman or Duplicate), you may gain it from any pile where it's the top card. For Swindler, the attacker chooses which pile the gained card comes from.
-When something asks you to return a card to the Supply, you return it to the card's ORIGINAL pile (these can be tracked using the randomizers), not a different Kingdom pile that happens to have those cards in it.
-Adventures tokens placed on a Kingdom pile only affect cards represented on that pile's randomizer (this is slightly different from the official Adventures tokens rule, which says all cards from that pile are affected, so uh errata? This change still allows tokens to affect multiple cards from the same normal split pile).
-Tower checks the randomizer of empty piles and only cards that match those randomizers are counted.
