I like this theme. A set of Equips that can rotate from each other for different situations, like an utility kit or belt. All it takes is any Warrior to Summon the Link monster to grab a tool and start the switching.
The Equips are not overly powerful, lacking any sort of immediate removal or negation, but one should be looking at their versatility. Instead, the power is in the support Spell/Traps, which I appreciate them not being actual archetype members or else they may be searchable or otherwise supported and make things a bit too easy, even if it's something the meta could handle. They actually are generic and work with any Equip Spell, making them easier to splash along a Switch Weapon package in a Deck that relies or runs Equip Spells.

I noticed an issue in the Counter Trap: the last effect requires a "Strike Weapon" but these are "Switch Weapons". This is most likely a typo.
