Phantaso

Tell me which cards i should replace it with, too.

your deck is %64 black, more swamps less forest i guess

No need for Nivmagus elemental. you should put nivix cyclops, searing spear and shock

But i will put x2 Latch seekers and x2 artful dodge

Maybe artful dodge helps better. Thanks for the suggestions.

Well these are the first things that should be done if the cards are found ;)

There is no need for banisher priest, goblin shortcutter,guttersnipe,warmid infantry and pacifism. You can use oblivion insted of pacifism and mizzium mortars are better than flame slash.
Boros elite, Legion loyalist, Frontline Medic, Spark trooper should be x4. You may choose one of Wojek or vioshino and make it 4 too maybe both. And 2 Tajic maybe and Aurelia, The Warleader if you want. Also add legions initiative, its a bit expensive but very useful.
Im not very good at suggestions but i would be glad if this gave some ideas.

-2 wolfir +1mountain +1 farseek

I agree that ramp isnt enough. Added 4 zhur taa druids 2 farseek and 1 forest. Removed 1 ruric thar, 2raiders and 4giant growth

This one maybe give some opinions http://www.mtgvault.com/phantaso/decks/golgari-w-vraska-the-unseen/

Yeah thanks

A land maybe since the costs are low and the artifact

This deck can produce high amount of mana so i think primordial is better since kalonian comes with 4 but hydra will come like 9/9 or something.

Merrow commerce is like vigilance for all merfolk

Merrow commerce and cavern of souls

yeah 1 eff for 1 mana and 2/3 that OP card.

oh yes nighthawk pls ban

this is the changed one, maybe better to analyse

-4 Syndic of tithes +4 Tithe drinkers thats all

SOrry Isolated chapels :D
