@hierarchnoble I get it, I mean I play Living end in modern and combo infect in legacy. Both these decks have a combo win but also a backup plan where they can just go face with dorks as needed, since at the end of the day the deck are creature based.
The difference to me though is that the power level in those formats and with those cards is such that it affords you more opportunity to run the backup plan, and the counters to the combo are not commonly maindeck cards. When Living end gets turned off in rounds 2 and 3 because your opponent sided in grave hate, you still have what amounts to a 3 mana wrath of god. When infect cannot combo you still have a deck full of evasive creatures that do unhealable damage and get in effect double power from pumps. Goblins in vintage for the most part gets you a bunch of underpowered goblins that afford you no disruption to your opponents potential combo kills. It just does not seem well suited.
You are correct in that it does not make sense to explain an untiered Vintage Aggro-Combo deck to someone who plays an untiered Aggro-Combo deck in both Legacy and Modern. I will refrain from discussing those formats. What I would like to say is that you continue to present the "always had it" mentality from your prior posts. If I present a plan for how to win against Force of Will, you'd point out that it's soft to Abrupt Decay. If I include that, you'll cry foul that we're soft to Workshops. If I include a card that blows up Sphere of Resistance, you'll point out how we're already dead to Yawgmoth's Bargain before we can cast it. FCG is not seeking to be 60/40 against the field, and there will be bad matchups no matter what. I don't know what you play in Vintage currently, but I'm sure it's soft to something too. When it comes time to design the 60 and the 75, we will pick and choose what makes sense and make adjustments as the metagame evolves.
