I'm sorry to jump in so early, just to say, I love the idea of "stampede". I like how it's a combat mechanic I haven't seen exactly before, and provides a new sort of evasion, and feels "stampede-y".

(I'm not sure, it may need to key off non-stampeding creatures instead, or something, so it does something when you only have one of it, else it's hard to play, but I don't know, it's premature to wonder about that without seeing some examples)

the way stampede is worded at the moment doesn't seem to make a whole lot of sense

is it meant to be "Creatures you control without stampede can't be blocked unless all attacking creatures you control with stampede are blocked"?

No, if Worldtrembler Rhino, Lounging Hippo, and Nomadic Scholar attack, you can't declare a blocker for Worldtrembler Rhino unless you also declare one for Lounging Hippo. Nomadic Scholar can be blocked regardless of whether or not you block Lounging Hippo and Worldtrembler Rhino.

Oh, so it's a mechanic that does nothing if you only have one card with it on the table? That's unfortunately parasitic.

I would extend Stampede just to "all creatures," rather than "all creatures with stampede."

I also think "fetish" would work better as a keyword than an ability word. It would allow you to make the rules text of most of your fetish cards more understandable, and possibly more concise.
