@smmenen if you’re going to quote someone, at least quote them. I think you misinterpreted exactly all of what I wrote in the post you were attempting to quote.
Ummm. I literally used the quote function to quote you verbatim. I did, actually, quote you.
I am pointing out that the concept of “power level” is non-existent as you conceive it & hopelessly contextual, and therefore a terrible ground for restriction. If PO were that powerful, it would be banned in Legacy like Gush & Treasure Cruise. It’s not even close.
In your own post this becomes evident as PO does have to be built around to maximize:
It doesn’t require much in the way of special deck-building, intelligent play, or complex sequencing. You just play cards you’d play in your blue vintage deck anyway (aside from Mox Opal), you get to stop playing expensive sorcery speed cards (like Tezzeret) and the most commonly played anti-combo and anti-shops cards aren’t even that good against it. Unlike Bargain..
Actually, it’s exactly like Bargain in that respect. You need more accelerants to support & maximize it. And, yes, Bargain generates mana via card advantage.
We restrict cards primarily in Vintage based upon tournament performance. Anything less risks harming the competitive balance & diversity of the metagame.
In addition to being the first good deck in ages to knock Shops off its perch, PO has brought big blue decks with Tinker, Yawg Will & Time Vault back to the center of the Vintage metagame. That is a GREAT thing. This deck has been virtually absent for almost 5 years, and the format has been stuck in the nightmarish quagmire of Shops v Xerox. PO is helping break that open.
The Vintage format is better now than at any point since Khans of Tarkir. PO is the reason.
