so i pretty much came up with a list of  dark zoo
4 loam lion
4 goblin guide
4 lightning bolts
3 dark tutaledge
4 birds of paradise
4 vengevine
2 spikeshot elder
4 doom blade
...
ok well thats all i got its like super half assed but i really think if i put time into it, it should be good. i like the speed of the deck and the fact that everything costs so little makes me not afraid to play dark tutaledge...i cant ever spell that card right. yeah so i can play it and not worry to much. i also considered putting in a pair of inferno titans as a finisher, it can clear the way for my creatures and to get in for lethal late game. i also have the doomblade for to clear the way and lightning bolts to deal finishing damage or own their creatures as well.the only problem is that the creature quality is not very high. the only reason i have birds of paradise is to snatch up vengevine from the grave and play tutalege...or i could even put in the shaman and squaderon hawks and just go from there...hmmm.i dunno.
right now i am considering just running my coating metal deck just R/G and adding more removal and maybe baloths. i even considered making it JUND  coating becuase i have a better removal set up, i can run memoricide, have grave titan or wurmcoil or even inferno titan as a finisher as well. inferno titan is pretty overlooked and right now all the creatures decks are starting to emerge again with vampires, boros,goblins, elves...so many out there, inferno titan is the bees knees.
i have also been trying to make necrotic ooze work and i really like the cards that support him work. so far my favorite card he works with is geth... the quality of this post is drifting becuase i am thinking of the two decks so i am going to let it go for now...
