:O dont take out the 3rd Spy to add Descedant. Descedant is a useless card without gravekeeper that's why its used when you have 3 Spy's.
My fixes
+ GK Guard
+ GK Descedant
to complete the engine
Other fixes
-2 Raiza
+2 Mobius, Thestalos or Caius
I would completely take out the Flamvell Engine. 1 Flamvell Spellcard (dunno the name
) is very dangerrous if you dont have the flamvells in your graveyard. And Firedog s just good to get out stardust, but nowadays people tend to play alot of traps. And without Flamvell you draw those weak tuners which arent that good.
