Chain (チェイン Chein) is a keyword ability found on ARTS, first debuting in WX-10 Chained Selector.

Chain (cost1) (cost2) (This turn, the next time you use an ARTS, the cost to use it is reduced by 1 (cost1) and 1 (cost2))

ARTS with Chain reduce the cost to use the next ARTS, and only the next ARTS, during that turn. This is forced: for example, if you use an ARTS with Chain, then an ARTS that costs Colorless × 0, the Chain is used up and the cost of subsequent ARTS will not be reduced. Chain does not affect the ARTS it is on.
