As long as Ratonhnhaké꞉ton hasn't dealt damage yet, it has hexproof and can't be blocked.
Whenever Ratonhnhaké꞉ton deals combat damage to a player, create a 1/1 black Assassin creature token with menace. When you do, return target Equipment card from your graveyard to the battlefield, then attach it to that token.
You don't choose a target for Ratonhnhaké:ton's last ability at the time it triggers. Rather, a second "reflexive" ability triggers when you create an Assassin token this way. You choose a target for that ability as it goes on the stack. Each player may respond to this triggered ability as normal.

You may target an Equipment card with the reflexive triggered ability that can't legally be attached to the Assassin token. If you do, it will enter the battlefield unattached.
