Fallen in love with Mardu Ascendancy and looking to represent the horde at FNM.

Here is how the deck plays out in Magic Christmas Land:

T1 = Tormented Soul or Bloodsoaked Champion

T2 = Signal Pest and Loyal Pegasus. Swing for 1/2 damage with T.Soul or B.Champ

T3 = Mardu Ascendancy or Rally the Peasants. Swing for 11/12 damage (total damage is 12-14)

T4 = Butcher of the Horde cleans up house.

Problems:

The Mana Base and Mana Curve are both terrible. If there are any math wizards out there I would really appreciate some feedback. Or a link to a website where I can learn basic stats. Links anybody? I am more than willing to read stats books if you can recommend one. Stats is fun :)

Card by card analysis:

Loyal Pegasus: best played on turn 2 to be followed up with Mardu Ascendancy or Rally the Peasants. Bad on T1 because only Nether Traitor can provide the extra attacker for T2

Tormented Soul: best played on Turn 1 or 2. unblockable 1CC creature. Reliable Mardu Ascendancy/Loyal Pegasus/Bloodsoaked Champion trigger

Bloodsoaked Champion: best played on Turn 1 or 2. Recursive ICC creature to provide Tymaret/Butcher some cannon fodder

Signal Pest: SUPER STAR! best played on Turn 2 because it cannot deal damage solo. colourless and battlecry is powerful with all the goblins that Mardu Ascendancy produces

Nether Traitor: I don't like this card. Its a slower, weaker B.Champ. But at least it is unblockable. The 2 Black CC is awkward as well.

Bloodghast: Acts as Nether Traitors 5-8. Imagine ditching 2 of these T1 to Faithless Looting. Again, only in Magic Christmas Land.

Faithless Looting: Improves card quality by ditching the recursive critters and spells to dig for mana and Ascendancy

Butcher of the Horde: Late game winner (Turn 4). Sac those useless Pegasus or goblin tokens for a super demon!

Mardu Ascendancy: its.. so.. drooling

Rally the Peasants: Meh.. Worse than Butcher for the Turn 4 win swing. Feels like overkill and it is a dead card if my creatures eat removal (same as Mardu Ascendancy and 1 potential dead card is enough). Butcher is at least a creature that can provide damage on its own.

Possible replacements are Immortal Servitude, Return to the Ranks, Lingering Souls, and Tymaret, the Murder King

All feedback is welcome :)

What if you revamped your creature shell to exploit that the Ascendancy tokens are red Goblins?

ex:

//Creatures: 34
4 Foundry Street Denizen
4 Goblin Guide
4 Signal Pest
4 Legion Loyalist
4 Bloodsoaked Champion
4 Goblin Piledriver
4 Goblin Chieftain
2 Goblin King
4 Butcher of the Horde

//Spells: 4
4 Mardu Ascendancy


Maybe GG could be Pegasus (more budget friendly). But a lot of these creatures synergize better with Ascendancy.

Foundry gets +1/+0 for each token produced.
Loyalist gives them first strike, trample and evasion.
Pest (if stacked correctly) gives them +1/+0 as in your list.
Piledriver (if stacked correctly) gets +2/+0 for each token produced.
Chieftain gives them +1/+1
King gives them +1/+1 and mountainwalk (often makes them and your team unblockable)

Altogether, I think you get more damage output from the tribal synergy than from running weak cards like Rally the Peasants.
