On the gatherer Dark Ritual is not modern legal.

Thanks @ZOMBLES127 ! I actually had a copy of Damnable Pact in the first version of the deck as a nice finisher indeed, but i cut it in the process of trying to make it faster and more consistent :) it's still on the maybeboard though !

@Talus21 Oh really ? I had no clue, where can i find an official list of banned cards ? I tried looking by myself and didn't see Dark Ritual on the ban list. I'm confused

Gray Merchant of Asphodel would be a great card for side board. It would gain you any life you lost against aggro or burn decks.

Comicaz I found it here

Possibly Fate Unraveler? I don't play too much Modern, so I don't know how good it would be.

Thanks Talus21 i checked and it is banned indeed ! Any good one drop replacement for Dark Ritual in your mind ?

@RovkirHexus I tried Fate Unraveler already and it didn't turn very good, as it is very slow. I'm trying to build my deck in an aggro-ish way and this doesn't suit very well, but it is in the maybeboard ! Thanks for your suggestion

Maybe splash blue? It has good cards like Fascination, Day's Undoing, and Dictate of Kruphix.

You also need better removal. Currently, you can only kill white, green, and black creatures. Maybe get rid of Deathmark and Dark Betrayal for Doom Blade, Dismember, or Slaughter Pact? Doom Blade is the best black spot removal card, Dismember is 1 mana, and Slaughter Pact gives you time to get mana.

Please, checkout my decks The Pissed Off Librarian and Feast of The Mind they bith use a strategy similar to this one. You might find them helpful.

But im thinking, for your colors,Teferi's Puzzle Box

Currently it doesnt look to me like youll live long enough for this strategy to work? Maybe try some more control? For your colors, i recommend Dreadbore

Thanks @denjisx90, i removed 3x Inquisition of Kozilek and added 2x Dreadbore and 1x Thoughtseize. If you have any more ideas like this feel free to tell me :)

Hi i have deck with the same idea, but more agro/ creature based, you can inspire in it: http://tappedout.net/mtg-decks/master-of-the-draw/

Hi HansZ666, checked your deck ! Seems powerful too! I got some ideas for the mana base and Terminate seems to fit in my deck too, i'll have to play around with it to see if it can replace Dreadbore or Go for the Throat. Thanks for your comment

Comicaz be sure that Terminate is best creature removal in modern, only Lightning Bolt and Path to Exile can be same good (cause of that - why dont you play Lightning Bolt? it's most powerful red card ever), Dreadbore is maybe some sideboard card against planeswalkers, but i think that you dont need planeswalker removal there, cause you can redirect damage form Spiteful Visions.

maybe Underworld Dreams?

Thanks everyone for your suggestions, i made some changes to the deck and I think made it a bit more consistent. It still needs more playtesting but keep coming with the ideas =)

Icbrgr the first version of the deck included Underworld Dreams but i think it's too slow for the format and the 3 black mana cost is a bit annoying. Everytime i playtested it and had it in my opening hand it was a dead card because i had better things to play... But thanks for the suggestion !
