mana ramp would help out a lot maybe some cultivates, rampant growths, and maybe rite of flourishing

i like ur vampire deck a lot. check out mine. http://www.mtgvault.com/ViewDeck.aspx?DeckID=190460 comment please.

take out the other kalitas and put in a drana or anowon

you should maybe put in some myrsmiths to make some more myr tokens

you need to get more zendikar & worldwake vampires for power and some corrupts, feast of blood, and urge to feed, maybe blood tribute if he can get at least 2

i had a myr deck too, but i just took it apart and i would reccommand putting in some arrests, solemn offerings, and equipments. maybe think about some white creatures that might be high costs like sun titan, if you can find one, because he can bring back your little myrs when he attacks.

i like it but its mostly a green, white and blue deck. so i would take out the mountains and swamps

i like your deck a lot i would maybe put in a couple of white spells like arrest, war report and remember the fallen and safe passage so you can keep out your paladins and your other creatures if they try to kill them.

i love kors, they are so awesome. nice deck by the way

put in some eye of ugins so your eldrazi spells cost less to play
