The Skyforge

Whenever you cast an equipment or aura, create a artifact token named Skyforged Steel with "Equip {3}" and "Equipped creature gets +2/+1."

Whenever a modified legendary creature you controls dies, exile it and transform this card.

"The Skyforge? Aye, my clan-fathers have worked it since the first Gray-Manes came to Whiterun. Skyforge Steel is all the Companions will use, for good reason." - Eorlund Graymane to the Companion's New Blood
