this wont get you chychrun let alone him and another prospect. start with a unprotected 2023 first , Brandt Clarke, Alex Turcotte , a 2023 second round pick

Oh boy, you’re a newbie. Ok, first, Carcone isn’t a prospect, he is an AHLer. The reason he is include in this trade is too balance contract. Since you are new, you probably don’t know that the maximum NHL contract allowed per teams is /50. Second, Durzi is a young RHD NHL ready.

The counter offer you made is super unrealistic
A top prospect Center who was picked 5th OA + a top RHD prospect picked #8 OA + a 2023 unprotected 1st RD pick (when ARI have already too many picks in 2022) and a 2nd RD pick is unrealistic for Chychrun

Considering Eichel got a middle 6 forward in tuch, a solid prospect in Krebs (although he's will not be an impactful 1rst line center) and a top 10 protected 1rst rounder+2nd, this deal is pretty much perfect imo. Chychrun is an offensive gifted dman but he's far form being that guy you can trustfully put in every situation just like Mcavoy or Heiskanen for example.

I agree with you in that the deal above is probably not enough for Chychrun.

However you jump off the deep end with your counter offer. Brandt Clarke is off the table. An unprotected 1st is off the table. This isn't McDavid being traded, and you're asking for a higher return than Eichel, who had even more term left on his deal.
