well, I think the person that you recall playing reanimator at that specific D4D was Rodrigo gonzalaz (don't know how to spell his name)... there are several advantages his build has over yours.

first of all he runs deed (which murders almost all hate cards as well as crushing aggro).
you run no form of protection aside the 4 fows which I doubt will be of any significance in a match.

he also ran a good number of discard spells that allowed him to either produce more threats or clear the way for his immediate threats.

you literally have only 4 ways to get your dudes into the yard... Meddling mage ftw?

you have access to black, which has many awesome ways to put your dudes into the yard.

1st: putrid imp
2nd: cabal therapy
3rd: zombie infestation

Rod runs 2 of these along with the black dreams (discard x deals x to each creature)...

the sutured ghoul rout is also overall weaker.

he can kill the turn after he comes out, but 1 swords and he becomes a 3 for 1 in their favour (you remove the dudes in the yard and then they swords him).

additionally, you only have about 8 ways to get your guy into play in the first place...


I used to play a GB build

the reanimation spells were:
4 reanimate
3 exhume
3 animate dead
2 recurring nightmare
