(FGO) Mississippi Mythisizers CQ - The Walls of Constantinople shall not fall!
So the idea here is to make Constantine work with as little as possible, Martha is here specifically to remove crit buffs/card resistances, a small heal and help Marie clean up.
The real tech here is Marie, with her having a small heal on NP tied to overcharge it's just enough to keep Constantine going.
of course the only reason this strat works is Caster's high np gain on hit and Daikouken specifically having high hit counts on everything, thus enabling Constantine to almost always having his NP raring to go.
It's a war of attraction and I made sure to stack the odds in my favor :)
