A whoooooole lotta math.

Alright, to put this gigantic ass block of calculations into words. The probability of you riding out the entire chain is 39.3%. Ignoring 1 Grade 2, you have a 71.6% chance to ride the Grade 2 if you run 2 of it, a 77.4% chance to ride it if you run 3, and an 82.2% chance of riding it at 4. Because the difference in probabilities between 3 and 4 are so little, it's more than justifiable to not run 4 if you can find something more worthwhile to take that unit's place. I can only recommend to use 2 if you aren't totally reliant on your Vanguard being at 11K defense. Also, with this sort of deck, the grade ratios required for a consistent deck are (assuming you are running 4 of the Grade 1 of the chain) at least 12 Grade 1s, at least 7 Grade 2s, and 8 Grade 3s, leaving 6 open slots (hopefully Grade 1s and 2s) open for player preference to mess around with.

If there are any questions at all about Second Generation Ride Chains, please ask so here or in the request box, and I'll try to answer logically or with math as soon as I can.

(the rest of this article is just mathematical proofs of my work, you can entirely ignore them unless you too are a mathematician and want catch any mistakes I might make)

~To note, all these probabilities assume you are going first with 4 Grade 1s and Grade 3s of the chain in the deck with a mulligan of 3, and 1 damage per opponent's turn.

**The Probability to Ride From Grade 0 to Grade 3:**

**Grade 1:**

Probability to not get the Grade 1:

55.7% chance of getting the Grade 1 by turn 1.

To set up a consistent deck ratio, each possibility to ride a grade should surpass 92.8%

Grade 1s required to break 92.8%:

12?

12.

Grade 2s required to break 92.8% (3 Grade 2 form)

3+4?

(crap, I accidentally deleted the numbers)
