Cannon Fodder Advice?

[Oleander]

So I'm wanting to do a move called Shield Guardian. These are basically, as the thread suggests, cannon fodder. They are expected to be destroyed and their fodder even suggests they are a "disposable sidekick with no moral drawback." I have three ways to go about this, that I'd like advice on gauging pros and cons of.

1. Move: This is the original idea. It consists of manifesting up to a maximum number of Shield Guardians, similar to the Zombie example, but with higher defense and no attack. It is given a target to either "Protect" or "Thwart" but beyond deflecting attacks it does little else, and does so until its destruction, or it is reassigned (manually) to another target and respective action.
   
2. Forces: I could just wait for Forces and make Shield Guardians my tanky forces, with an enhanced version (Glass Sentinel) as the Prime Force over them.
   
3. Forces + Move: The Glass Sentinel could be the Force, which has the Move to create Shield Guardians.
   

I'm leaning toward #3 myself, considering a Glass Sentinel would make an awesome sidekick. Most likely the entire "force" would consist of 1 Glass Sentinel, instead of 5.
