May I suggest adding the "goal" of the deck to each list? (is the deck made for pvp, arena, fg etc)..
OTK work for example exceptionally well vs fgs - yet in pvp people adapt too quickly & can actually be easily countered. Similar quite a few of those decks will not beat fg yet are strong options for pvp.
Also maybe add instosis as upped OTK example: I think it is quite an "easy" to figure out OTK, and can hence serve as example for OTK. Though for OTKs there's little room for really modifying the deck without redoing it
. And I think instosis should be considered "legendary" already, given how much it changed FG farming
. Also the OTK you showed there I wouldn't really play as OTK, dragons often have enough hp to withstand quite a bit of CC: and I think that deck would actually fare better if you just build dragons asap :/. But that's me
