Excallibur's list is complete... Note that Shakra is Courage based though.
BTW, if you're trying to put together a Stop All deck, be sure to give us (or at least me) a shout as to how it plays. I've been wanting to put together a Roots-Nightmare Stop All deck but just can't afford it. Nahi alone is worth more than my entire deck! lol...
My preliminary idea is:
Roots - Shakra, Nahi, Yookie, Miken Moose/Arno
Nightmare - Glorg, Dieter, Eadh, Sarg/Timmy
You can easily tweak the above deck to include Ratanah or Kenny if you don't mind a potential 3 x 2* draw. Nightmare-Gheist would be more affordable but Morlha isn't really playable.
Yep, stop all deck
dieter glorg kenny eahd (13*)
Shakra Nahi CR Miken Moose Arno (12*)
Problems are as you said, Price and it seems stop all cards are really obvious. Gonna need to think of a good tactic to (ab)use them.
I could do a gheist halfdeck of
Z3r0 D34d Methane Luba Leviatonn (12*)
But it seems almost silly to go roots gheist.
