I went and tested what non-transcendent projectiles Dragon Fang Shot clanks with if you still wanted to know. Basically it was this:
Mechakoopas,
Crash Bomber,
missles (both regular and super) and
Lloid explode on contact with DFS.
bombs do as well, but they'll beat out uncharged DFS (like how they do with Thunder and Arcthunder).
Gordos,
soccer ball, and
can all get knocked back when hit by DFS, like they do with mostly everything else.
Thoron,
Shadow Ball (max charge), and
Charge Shot (max charge) all beat DFS out.
Aura Sphere (max charge) does too, but only if at high aura for some reason (minimum 140%, though it might be lower, I didn't really check, but it needs more than 100% at least).
Then there's
fire breath (which aren't exactly projectiles but) and
Autoreticle, which also beat out DFS. I imagine that these win for the same reason that Thoron does: they're multihit, and so the first hit clanks but subsequent hitboxes make it through since DFS has already been canceled out.
Pikmin cockblock but get killed by (a fully charged) DFS.
uncharged shurikens clank with DFS, but a fully charged Water Shuriken actually beats it out. I thought that fully charged Water Shurikens were transcendent though?
peanuts lose to DFS.
All of
bonus fruit clanks with it up to Galaxian, which wins, as does the Key and I think the toaster (or whatever the hell the yellow thing between Galaxian and Key is).
Everything else I tested clanks with it (including itself). The only characters with (non-transcendent) projectiles I did not test were
since I don't have them, as well as Mii Gunner's other projectiles and Mii Swordfighter's projectiles cuz I got lazy at that point lol. Oh and
because Din's Fire
sucks is weird and I sometimes forget that Phantom is considered a projectile.
