Thanks! At the current point, this is where I'm thinking it goes, with cards being sorted into the following theoretical categories:

True X-tier category (this pertains to characters that are almost necessarily leads and that you have a strong incentive to use at the higher/highest levels you can independently of their base stats): Bane/Luchador;  Batman/Arkham Origins (he perhaps has more "reliability" on offensive defense teams that the former does not, as he is basically a weaker BAK who yet always choses the two bar option; otherwise, the two can be redundantly paired).

True top-tier category (based mostly on total base stats and still significantly on passives, very rarely on individual moves): Ares (perhaps fitting in the above category); Batman/Arkham Knight; Batman/Dawn of Justice; Darkseid/Apokalips; Deathstroke/Arkham Origins; Harley Quinn/Arkham Knight; Martian Manhunter/Blackest Night; Scorpion/Mortal Kombat X; Sinestro/Antimatter; Superman/Dawn of Justice; The Arkham Knight; The Flash/Metahuman; Wonder Woman/Justice League; Wonder Woman/Dawn of Justice.

Honorable mentions to true top-tier: Bane/Arkham Origins; Batman Beyond/Animated; Black Adam/Kahndaq; Hal Jordan (Green Lantern)/Red Lantern; Martian Manhunter/Prime; 3x lead Red Son teams; Superman/Godfall; Static Shock; The Joker/Arkham Origins (not statistically, but strong heavy attacks, modest passive). Super-honorable mention: Reverse Flash.

True support+power category (these are characters with the best support abilities who either for their abilities or some other trait can be dominant at the highest levels of play, but can otherwise be  E0 or EVII when paired with others of equal or higher rank ):  Batgirl; Batgirl/Cassandra Cain;  Killer Frost/Prime;  Raven/Prime. Perhaps others.

True support+function category (these are characters with the best support abilities and other desirable traits, these last such traits requiring they be used as leads to be fully exploited): Catwoman/Batman Returns (S1); Harley Quinn/Animated (S2); Lex Luthor/Krypto (S1); Killer Frost/Regime (S's); 1x/2x Red Son supports; Wonder Woman/600.

After all of this there is the relative X-tier and relative top tier: these are characters with good passives but not base stats, and so who you would promote as to have the most relative power. The relative X-tier includes Black Adam/Regime, Cyborg/Teen Titans, and Doomsday/Containment. These can perhaps even be promoted to even EVII if just used with weaker cards to accentuate their relative power. (Doomsday/Containment could be used with a weaker/equal Batman/Prime, for instance, as Harley Quinn/Animated is usually thought to outclass the latter, but as Doomsday/Containment may favor Batman for his own passive providing a set amount of power.)

There is also the true mid-tier, which is defined by true statistical limitations (i.e., the "silver barrier). You might want to keep some gold level cards at around the same power as your Nightwing/Regime, for instance, who you might otherwise want to max because of how powerful he can be against equals or even those slightly stronger, who he can effectively suppress to fighting within his preferred range (i.e., basic attacks).
