ok, we agree.
so, here's my list, with 3 pyro maindeck to make a TEST.


MANA:

10 Mountain
4 Ancient Tomb
4 City of Traitors
4 SSG
4 Chrome Mox
4 Seething Song
---

LOCK:
4 Chalice of the Void
4 Magus of the Moon
3 Blood Moon
0 TRINISPHERE
---

WIN:
4 Rakdos Pit Dragon
4 Gathan Raiders
3 Arcslogger
2 Sulfur Elemental
2 Umezawa Jitte
1 Sword of Fire & Ice
3 PYROKINESIS
--------------------------
Sideboard:
4 Crypt
3 Pithing Needle
2 Powder Keg
1 Blood Moon
4 Trinisphere
1 ???


-----

Pros:

-Pyrokinesis MD has sinergy with Hellbent
-3 Blood Moon MD
-Easier Chrome Mox pitch
-Removal and Finisher
-Trinisphere slows Jitte
-Better than Demonfire

Cons:

-Jitte is a Win Condition and we don't draw so 3>2
-Trinisphere can win game 1 and make your opponent go crazy as a come_into_play effect, Pyrokinesis can't.
-I LOVED the balance between Trinisphere and Blood Moon split (2/2 each)
-Sideboard now sucks.

----------------------------

So basically I love the board controll option and burn finisher hellbent friendly that Pyrokinesis can give, but I miss the balance between Sideboard and Maindeck that Trinisphere and Blood Moon had.


PS:
what if I put 2 sulfur elemental SB, restore the 2/2 Blood Moon/Trinisphere balance and 3 Jitte, and use 3 Pyrokinesis?
I'd have the same number of red cards and get rid of a card with a very little sinergy..
