Thanks to Aymanu of course, but drawing conclusions from statistics processed this way is foolish.
Dungeon is a strong faction, and it is mainly used against other strong factions: Conflux, Necro, Ramp. And this is exactly where its unevenness and the need to know how to play it come out. The same can be said about Necro.

Castle - yes, a stable faction, but it can be called strong only on 3 templates: Balance, Panic, Jebus Cross - again, the templates played are not reflected at all. As it is, its main positive balance comes in the matchups: Castle-Tower, Castle-Barb (speaking of SoD).
Etc.
