I did it without any guides back in the day you don't really need them, just use champs who can crit a lot (or with guaranteed crits) it's easier now cause we have more champs than we did back then. Just to name a few: Shang Chi, Hit-Monkey, Kitty Pryde, Shuri, Mantis, Bullseye, Morbius, Ghost, Mole-Man etc (I just thought about Kate too since she can apply fragility and critical coldsnaps but I haven't tried it myself, might be worth giving it a shot though if you don't have the others). As for destructive feedback two options, if you're good at light intercepts do just that, otherwise just wait it out and don't attack him so you can parry with no issues.
Following up on advice from @ItsClobberinTime which is generally accurate.
Kate probably not the best option here - Crit Me With Your Best Shot will prevent her Coldsnap and Caltrops damage.
Other skill champs with high Crit rates are worth considering; like Stealthy, Falcon, Misty Knight, Elsa and Awakened Masacre; although remember their debuffs won't do damage, either.
Use Stark Spiderman. He has the taunt which will force CAIW to use specials and don't get to sp3, if necessary and only when the shield is down, heavy to power drain, Sparky has high crit. Other options are Scorp and Spider Ham for the taunts
Awakened Kitty Pryde works great, but it is a slow fight. Just build up to SP3 and throw when CAIW gets his. Easier with Tigra synergy but not required. Ghost with Hood synergy works too and is much faster, but not as safe because Ghosts phase timer is much shorter than Kitty's. Ghost does not need Wasp, and as long as you keep his passive furies low you are safe to parry and take some blocked hits to bait a heavy to throw the SP2. Wasp just gives you free openings.
Those are the two I would recommend if you have and know how to play them.
