List starting from Sean McKeown's article: http://www.starcitygames.com/article/25835_Pod-People.html. While I currently really like Sean's Lotus Cobra and Domri Rade Tech, I have not yet seen the magic of Vendilion Cliques over more Restoration Angels and other stock creatures.
Large debates remaining in the deck:
Domri Rade vs. Chord of Calling: It seems like Domri is better for a plan that isn't "all in" on using Pod to win, whereas Chord fetches specific, low CMC utility creatures. Also Domri gives another creature kill option, albeit generally at the expense of my own creatures.
Sideboard Creature Bullets vs. Trinket Mage + Artifact Bullets: Creature Bullets (Phyrexian Revoker, Loaming Shaman) are Podable, Chordable, and can be revived from the yard via Reveillark if necessary. They also can't be countered if Podded in. The Trinket Mage option costs one more slot in the board, one more slot in the deck when it's sided in, and the artifacts can be countered when cast. The artifacts can be more resilient, however, in that they don't die to pyroclasm, bolt, or path. Ex. Pithing Needle is more resilient than Phyrexian Revoker in the GR Tron matchup. It also allows graveyard hate at instant speed (Tormod's Crypt versus Loaming Shaman) for things like Eggs. Also this package allows some options that don't have creature equivalents, like Engineered Explosives, which is good against Eggs and U/W/R.
