I believe there are calculations done by our SP team.
Initially there were beliefs that the 3 warrior thing where hp to dmg does alot of dmg boost, but after it is out, the boost seems at best insignificant?
As such, one would wonder what then is the optimal set.
Would the undermentioned deck selection be considered optimal?
For example, if one has a 100% ignore pdr, then maybe the optimal set may be
Deck 1 and 2 - Bucc, pala, Marksman/Jett
(depending on whether if they have 100% crit -2 mm to boost crits, 2 jetts to boost min crit dmg)
Without 100% ignore dmg
Deck 1 - Bucc, Mech, jetts - pirate set
Deck 2 - Ds, paladin, aran/dk - warrior set
For Survival / Mulung
Deck 1 - DS/mech/bam (buff duration increased, status resistance, and dmg taken reduced)
Deck2 - Evan,Merc,Aran (passive mp, hp drain , + cd reduction)
After AB,Kaiser, and the 5 novas are out
assuming each nova adds 10,20,40,80 primary stats
Deck 1 and Deck 2 - Bucc , pala and their respective nova
(i.e a Hero will choose 2 kaisers for both decks)
For Dmg without 100% pdr
Deck 1 - Bucc, Jett/AB/ Mech ( 3 Choose 2)- Pirates set
Deck 2 - Bucc, pala, Nova job
For most damage dealing mains,
It is recommended to have 2 paladins, 2 Buccs, 2 (class of their choice) for the most optimal buffs?
Having said that, in general the damage buffs from card system is imo not that significant.
However those buffs like crit chances - does help in getting phantoms to 100% crit.
While an aran and evan does go a long way in helping one complete mulung dojo.
As for the status resist buff from ds, this is more obvious when one is attempting to solo things like pink bean, cygnus instructors with a class like say hero or a dark knight.
As such, although mathematically there may exist an optimal choice of deck but I believe that the boost from the optimal deck may not be that significant in terms of damage, although 2 mm does go a long way in helping one to achieve 100% crit as a phantom.
