Grave Swordsman: I'd say maybe bring down his ATK to 2000 or 1900 and it'd be balanced.

Ring: Edit one little bit: "If this card has three or more cards equipped [b]by this effect[/b], it gains the following effect..."

Tenancy: Do you realize how many cards have the word "Swordsman" in them that doesn't involve your archetype? Flame Swordsman, The Little Swordsman of Aile, etc.
