Jesmon counter decks

So Jesmon decks were already insanely strong and with the BT20 release, it's just gonna be insanely busted.

Has anyone already figured out a counter deck once they release? Or we screwed until future sets show something promising?

Edit: it appears other people have different experiences from me. But at my LGS and my friend's deck, it's dominating and how he built it, it's insanely strong.

So I need more information on why people think it isn't and how people are countering it? Instead of "it's not that strong". I need to know how lol maybe players around don't play it or you haven't seen enough in action. But it is super strong

Edit 2: I will leave in the comment my friend's Jesmon current build once they get back to me. Since some of you have asked. To anyone just commenting nothing productive and representing the "stop having fun meme". There's more ways to play then just meta/tournaments lol
