Rule 301.5e
Official source text from the 25 July 2025 Rules release
If an effect attempts to put an Equipment that isn’t also an Aura (see rule 303.4i) onto the battlefield attached to either an object it can’t legally equip or an object that is undefined, the Equipment enters the battlefield unattached. If the Equipment is a token, it’s created and enters the battlefield unattached.
