Round 2
BTC's judgements
Corv vs Wap

Response 1
Corv
* Thor is VERY strong
* Thor is durable
* Tak is strong
* Tak cuts good
* Tak is tough
* Cannonball isn't as invulnerable as while blasting
* Tian has meme striking
* Tian is very durable

Wap
* Cannonball will hit Thor before Thor can realistically ready Mjolnir to bat him away with
* Thor doesn't have great durability feats
* Cannonball's crashing feats are way greater than Thor's blocking feats, which aren't even direct durability
* Corv's anti-feat dump is fake
* Diamondhead is a spammer
* Tak attempts to block in-character which won't work against a spammer
* Diamondhead can pierce Tak, ergo with the combination of the above reasons, Diamondhead wins
* Cannonball is very fast and maneuverable
* Cannonball's blasting hits hard
* Tian sucks

Response 2
Corv
* Cannonball's attacks are telegraphed, ergo Thor can block
* Shummatsu Gods by nature are just durable
* Diamondhead IC will not use lethal force against Tak
* Tak can stop the barrage anyways
* Tak has good piercing resistance
* Tak will pierce Diamondhead
* Cannonball's characterization will not lend him to fighting super optimally
* Tian is a heavy hitter in context of the tier
* Cannonball's speed is probably not that fast to his own
* He can also be hit and taken out of effectiveness

Wap
* Cannonball can be faster than what Corv has stated
* Thor's hammer having massive reach means that he has to time it optimally to bat away Cannonball
* Wap calling out Corv's shaky god scaling
* Thor legit doesn't use electricity IC
* Thor has no visible durability to speak of, and no real way to deal with Cannonbolt
* Diamondhead WILL use lethal force
* Diamondhead's piercing is insane
* Tak doesn't always block IC
* Tian cannot physically react to Cannonball
* Cannonball hits Tian and he goes down
* The anti-feats are fake

For the sake of expediency, I am not going to include Response 3 in the usual style, but I will still factor it into my judgement. I think it's safe to say at this point however that Wap takes all 3 rounds.

For one, I think the issues with Thor are abundantly apparent. He has no good direct durability feats except he vaguely scales to the other Shummatsu gods which like... is really awful evidence on its own. Coupled with the fact he'll rarely use his electricity attacks, it basically means Thor's only recourse of action would be to time a bat against Cannonbolt, and then that would not even necessarily end the fight in his favor, whereas the reverse is absolutely not true.

Tak's kind of a bad pick from what I can tell both from characterization and actual feats he has to work with.

And last but not least, while I do think Tian was solid, it seems Cannonball edges him out.

Wap wins
