I doubt if there is a interaction that hasn't been found yet... but i am sure there is a lot of poorly explored ideas floating arround!!! Its just a question of brews, experimentations and pratice!!!
I started arround Tempest and i think the changes are imprenscindible to the game mostly because the power level is constanting rising, so balance is always needed!
Strangleroot Geist
Geralf's Messenger
Bloodghast
Gravecrawler
Any others??
With these heavy mana intensive creatures (GG for Geist and BB for Pox) one certain land is Twilight Mire, but i dont know how much lands i must run.
Chameleon Colossus is a very good Merfolfk/Wizard for this deck too!!!
