Hey man, if you want to splash a lil red in, Godsire. i know, no longer standard and stuff. but still, populate w/ Godsire is prette boss.

Get rid of sliver construct and put in pacivism

Chromatic Lantern

put in some duel lands that have red in it just so you can cast both halves of breaking and entering. Or, crumbling necropolis.

you know, Elite Arcanist might not be too bad of an idea.Goes along with Isochron Scepter

woah! this is awesome!

How about burst of strength? G: put a +1/+1 counter on a creature and untap it.
Rancor could be nice too for some more aggression. G: enchant creature. has Trample and +2/+0. if rancor is put into your graveyard, return it to your hand (something like that)

How about land tax, just to troll?

how about cards that get stronger or make other things stronger based on how many enchantments you have? like sphere of safety.

Ignoble Soldier

ok, then maybe add in the vivid lands? you know, with 2 counters T: remove one add whatever color mana. or T: add 1 to your mana pool (it could be any color depending on the vivid land you have. there's one for each color).

why vorel?

very nice. Maybe put in tutors to search for your enchantment instead? with axebane guardian and gatecreeper vine it would be easy to get the mana need to use the tutors. (Use shocklands, unless u can't afford them, then, well, guildgates will do)

he's also very easy to kill. any pinger card can kill it, any kill spell, any board wipe, lightning bolt, shock, etc...

take out coretapper (unless you can get 4 door of destinies) and put in moar lands.

idk if melek fits in to well. you don't have many instants and sorcery's to rly make it that usefull. i'd take them out and put in 2 more jace's phantasms instead.
Or, you could keep them in and maybe get rid of other cards and put in some tutors instead.

i once got a trading post in a draft, and it actually won me the game. I was mana blocked like crazy so i just discarded all my expensive cards and gained enough life to keep me in the game until i had lands to make a comeback. twas great.

hm... well, because it's black... you should add in Jace. Jace makes everything better.
Jk.
I do like the deck. I'm not sure what exactly to suggest cause i've never been good at making black decks.I do like mark of the vampire a ton (it's won me several games) but i also like the tutor, it helps you get the winning card you need in case you didn't get it. if you don't care what legality and you have money to burn, you could get demonic tutor :P

^That is a great card. I also like Pilfered Plans (1UB: draw 2, they mill 2) and Consult the Necrosages (1UB: draw 2 or they discard 2) but yeah, visions of beyond is great. look into that.

with my mill deck, i've always done worse when i use jace's +1 rather than his 0. :P but thats just my luck
