if my hida zaiberu is at home, can i announce Hidden Reserves and pay 3 gold, move Hida zaiberu in the battle, and then fail to attach Hidden Reserves, which then goes into the discard pile?
Hida Zaiberu Cannot attach Followers.
Hidden Reserves 3G Battle, * : If this Follower is in your hand, target your Personality at any location. If he would be opposed, move him to the current battlefield and Equip this Follower to him.

If you do this the attachment will fail, and Zaiberu will move the current battlefield.
