Anyway, realistically, if we're looking at them through ABC Logic, then Tyris should stand a decent chance, he's definitely a better swordsman then the likes of someone like Saesee Tiin, since he stomped Nejaa Halcyon, while Tiin would lose pretty solidly to AoTC Anakin.
Unless that opinion has changed.
Ventress isn't that impressive, she was on equal footing with AoTC Anakin way back when, and has gotten completely humiliated by Dooku (nothing wrong with that).
Ventress' best feat imo, is being able to beat Kit Fisto.
If AoTC Anakin is still considered comparable to Fisto, then Tyris is immediately > Fisto.
No one better dare come with the "Anakin wasn't serious when he was trying to beat Nejaa Halcyon", as they both trained specifically for the purpose of beating one another in sparring.
All that alone puts him into the league as a pure powerhouse, added onto that is the fact that its implied by Halcyon's vision that Tyris would have killed all 3 of them easily if Halcyon didn't kill him, and later on, this is reinforced by Desertwind claiming that he killed have killed any of them in saber combat, admitting that even two of them would lose to him.
But why do those guys mean anything? They're just randoms, right? Well, yes, but their feats alone already put them over "I, Jedi" Corran Horn through power-scaling.
It's confirmed in I, Jensaarai, that the two people that Desertwind and the other guy face are above the Female Saarai-Kaar, the same Female Saarai-Kaar that was solidly beating Corran Horn.
All this culminates into one thing, Tyris' superiority over Kit Fisto at the very least, if not, but probably above Ventress.
If you guys just can't see the simple logic behind this, I don't know what to tell you.
regard;ess aotc anakin isn't fitso level, and a pre-prime ventres(who was "growing every moment" has outmatched/stalemated superior versions of anakin anyway
