I propose to change it as following (bold) :WR: Reforge Anduril the Flame of the West, Belegennon, Ringil, and Horn der Herausforderung (Horn of Defiance). All reforged items are in play at the end of the game.
WR is indeed almost impossible to fulfill because lots of turns are needed.WR: Reforge 3 items among Anduril the Flame of the West, Belegennon, Ringil, and Horn der Herausforderung (Horn of Defiance). All reforged items are in play at the end of the game.
Reforging must be recycled because 4 are needed and Anduril cannot be reforged last.
Moreover items must be in play at the end of the game.
