A Johnny card if there ever was one, Wilting Touch does nothing on its own. It can buff a well-placed Arc Trail or cut down something like Dual Casting. It is incredibly expensive, but it’s strange versatility makes it appealing. Maybe it should be B/U and B/R instead of BRU so it’s cheaper, keeps its color identity, and can be cast for BR, BU, BB, or UR.
