Machinist's Arsenal Providing Power/Toughness After Azure BeastBinder
I was in a game of standard and i attacked with an azure beastbinder to make a machinists arsenal lose all abilities until my next turn. on opponents turn they play beatrix, loyal general and had a blacksmiths talent at level 3. they used either beatrix or blacksmith ability to equip the machinists arsenal despite it no longer having an equip cost (this part i think is fine). somehow their beatrix had 12 power though. they also have a dragoons lance and a Sword generated by the blacksmiths talent both equipped but that wouldn't make the 12 power make sense. I lost because of this

So long as the artifact is an equipment (which it still was in your scenario), it can be attached. Just not by using its equip ability, which was removed.
Furthermore, the equipment's ability gets a new timestamp when it gets attached (irrelevant here, but worth mentioning), and its effect includes a type change (making the equipped creature into an Artificer). This means, that in the layer system, the ability starts to apply in layer 4, before it loses all abilities in layer 6. And since it started to apply, it gets to apply fully, even though the ability is removed halfway through its application. So the equipped creature also gets the power/toughness boost.
