I will be play testing this today (4-7-15) with a total of 15 opposing decks of all different mechanics; including, but not limited to:
Pathogen: "I"
Fortis Mortis Apparatus
Core of Primordium
Vampyr: The Essence
Vampyr: The Thirst (not listed)
Posse
Champions of the Hereafter
Vermin
The Elf Belcher
Galvantic Siege
Nosebleed

I will update the charts as soon as the testing is complete.

Good luck!

The stats are in, and I'm very pleased!
I played two games with each opposing deck. This is not to be confused with best of 3.
Posse ran this over in turn 7 due to a bad draw and no transmute cards. The second game was better, scoring a Go for the Throat as soon as Krenko, Mob Boss hit the field.
Champions of the Hereafter took this deck with 2 Oblivion Rings- twice! Grr.
Everything else was defeated rather swiftly as I either hard-drew the combos in my opening hand or were able to win T5/6 with a transmute and problem resolution.
Again, very pleased.

I'd throw in a couple Creeping Tar Pits

No sir,
A previous version actually included these.The mana is slow, and for a 3 cost for the ability, I can't do that and pay for the guildmage's ability. Simply, too slow.
I had a similar issue with Ghost Quarter, as I was losing consecutively because of the colorless mana it produces. I needed specific mana, and fast mana.

Personally I would take out the Dimir Aqueducts since they enter tapped, and even cost you a land. Maybe replace it with the pain land Underground River or filter land Sunken Ruins.

Great suggestions! Alas, I don't own either one of these cards. I'll put them in my acquire board and if I ever get some they'll go in.

wuaaaaah? Bloodchief Ascension has made a home in this deck, the only reason its competitive. run 4.

CricketYT,
1. I don't have any.
2.That requires counters, to do 2 damage a turn to place a counter on BA would require several more turns for the wincon. Great for casual, not for competitive.

To bad Lobotomy isn't modern legal. Looks fun. +1

I feel like it is, in a way, Reap Intellect I think functionally is the same, but casts for one more, but every turn after that works better.

Sweet cards! I've never seen them before. Definitely up my meta of play. A bit expensive for this deck, but would go GREAT in my other mill deck.

Play tested some last night. Also, I found an error in my charts. I was missing a game from my turn tracking chart. All is fixed.
Was thinking of starting a new deck that's a little... Non-meta. Going to sit down with my cards later and see if I can't find any obnoxious, deadly, but mostly fun combos.

OH! You know what would go REALLY well in this deck? A retrace card! Use Raven's Crime early on and let your opponent forget about it, then combo when they don't expect it!

Ooh, I like the way this card makes me feel. It has the same flavor as the rest of the deck and is exasperating as it is devious.
I may consider getting a couple of these. Not sure if they'll go into the main or side board rhoguh. Thanks for a great suggestion, SorcerersBone!
