If a lower value gets completely negated by a higher value card, then the higher value card has stronger abilities, simple as that. That's literally what the card system says, and it's still not res negging cause you're using a higher numbered number that stops any lower value, that's just a layered hax.
It being resistance negation was already sufficiently proven though. Lethal Flame works on opponents who explicitly are resistant to time abilities and keyblade cards, alongside other cards having light and darkness concepts tied to them work on characters who are normally resistance to these things.
The very definition of
Resistance Negation is:
the ability to remove an opponent's ability to resist certain effects, allowing the user to then affect them with those abilities. In extreme cases, this ability can even override apparent immunity.
If a character can resist the abilities of the Keyblade and abilities that stem from light/darkness yet can still be effected by these things. It's negation and not higher potency. We know this is the case because Keyblade abilities don't work off the notion of "stronger = better hax" and instead have general abilities (which also applies to Light and Darkness in general).
There is no evidence of a "higher potency" here and the notion that it's potency was already debunked at that. Cards aren't just abilities but also the ability to do things and so on. This is why it was mentioned here that unrelated cards can still "break" other cards of lower value (Item Cards breaking Friend Cards for example), because this flies in the face of potency being what's happening here.
How does using an item have more potency than summoning... Yeah, it doesn't because it's not potency or has anything to do with the concept in general.
The only way it would be "layered hax" is if the number of the cards directly correlated to power and the likes. That isn't the case as proven before (aka,
this post), it's just merely value and has no direct correlation to potency (again, a Item Card can break a Friend Card, a Friend Card can break an Attack Card and the list goes on). These are clear pieces of evidence against the idea that cards are valued by potency
The whole point of resistance negation is the fact that you ignore their resistance regardless what their immunity is, even if you use a weaker spell and it works on them, that's resistance negation, if a weaker card that sora uses becomes useless because of a higher value card, and vice versa, that's not resistance negation, that's only layered hax, so for once give me something that has the cards ignore any and all resistance regardless if they have a higher number or not.
But where are you getting that Sora's abilities are higher spells or versions of certain abilities however? That's not indicated anywhere and again, values in the card system aren't measured in power as proven above. It would be illogical to really assert that unless you are trying to say that using an item has more power than summoning or a basic attack. Obviously it doesn't work that way and the value is just merely layers of resistance negation per the premise we indicated above
We've already given you that. Keyblade cards have the same abilities as a Keyblade and it effects characters who are normally resistant to keyblade abilities. How about the various light and dark cards (which has the same abilities that light and dark has within
this verse) still working on characters who are naturally resistant.
Even a Level 1 Card has negation for the reasons above and it only stacks from there like how indicated in the CRT itself. All in all, it's resistance negation and moving goalposts doesn't change that our premise is supported and yours is going off of a misunderstanding of the system itself
Anyways...
I admit I lost track of the debate because of the sheer amount of messages.
Can someone provide a summary of the two opposing sides' arguments?
My side: Cards provide resistance negation layers based on the premise outlined in the OP and the above, with such aspect not just being "hax layers" out of being entirely unrelated to physical stats in relation to suppressing opposing moves and resistances.
Glassman's side: Cards are "hax layers" because
there's an implication on that out of relying on numbers, even if that's not solid on its own (IMO, an implication is less solid than a proper statement or the like to say the least), and
semantics at play outweight his claim and just make it more assumptive over those just being resistance neg layers.
After a certain point the arguments mostly went in circles, so even if there's still a lot to read anyways, this is the most I can summarize the stuff without leaving out relevant details for the sake of evaluation.
BTW, credit to SuperBearNeo for considerably helping on the arguments.
