This is a combo control deck, that sinergy around the draw engine of Lich's Mastery, the mana engine of Blood Funnel and both in Priest of Forgotten Gods.
These powerfull enchantments take Phyrexian philosophy of trading life for cards (Phyrexian Arena) and creatures for mana (Phyrexian Tower), while the Priest does everything, even Diabolic Edict and Shock the opponent.
Lich's Mastery goes beyond trading life for cards, by first saying you can't lose the game.
It also has hexproff and three separeted triggers. The first says that you draw a card for each point of life you gain. Witch for exemple with Form of the Dragon in play means, when you have less than five life at the end of each turn, you gain that amount of life (if you are at 1, you gain 4) witch also draw that many cards.
The second trigger are the price for the bargain, that require cards in your graveyard or hand or permanents in play to be exile for each point of life lost. For exemple with Form of the Dragon in play means that at the end of each turn if you are at more than 5 life you lose that much (if you at 7, you lost 2) and have to exile that many cards.
The last trigger is the "fixing" drawback that means that if your opponent gets around the hexproff protection or the mastery is your last permanent and you are forced to exile it, you lose the game if it leaves the battlefield.
Blood Funnel make the non-creature spells cost less, requiring you to sacrife a creature so the spell does not get countered. Our sac fooder are Stitcher's Supplier, Gravecrawler, Fatestitcher plus zombie and elemental tokens.
Your one drop creatures act as "mana rocks" in a sense. Assuming you follow then with a turn two Blood Funnel, you can cast, on turn three, four drops like Nyx Lotus and Demonic Pact.
Our condition wins are powerful enchantments and walkers like:
Form of the Dragon;
Liliana, Dreadhorde General; and
Chandra, Awakened Inferno (that do not require a sacrife to pay for the reduced cost because is can not be countered.
