Can a unit with Weaponmaster attach an Equipment card that has no Equip cost?

Ruling: All Equipment cards in Riftbound currently have an Equip cost, so this situation does not occur in practice. If a card without an Equip cost were ever printed, Weaponmaster would be unable to attach it because the cost cannot be paid.

Nuances:

• Cards like Last Rites and Blade of the Ruined King do have Equip costs, despite different templating
• The templating difference ("Equip [symbol]" vs "Equip - [cost]") is purely a formatting choice: simple power-only costs are included in the symbol, while complex costs (power + additional costs) are spelled out separately
• Reminder text formatting can be confusing but doesn't affect the actual rules
