A good card for getting rid of anything equipped.

[I am Fate. Embrace me.]

Independence of the Knight
Spell/Continuous
When this card is activated, destroy all cards equipped to a monster.
Cards cannot be equipped to monsters. If a card is equipped, it is destroyed and the owner takes 1000 damage.

This card can be used to mangle machine emperors, and make a negative effect for Phoenix Gearfried. And Super Vehicroid Stealth Machine?
It won't be attacking multiple times anytime soon.
