Is it Capping Season? Sadistic Sacrament, Jester Cap, Nightmare Incursion, etc.

"Capping" is an old head reference to using \[\[Jester's Cap\]\] to strip win cons and cripple a deck. If you recur the cap you can actually mill someone out too but the main use, AFAIK, was win con sniping.

I mentioned \[\[sadistic Sacrament\]\] in a general EDH thread as a general "neat things we like to do in EDH" and it occurred to me that CEDH decks might be so streamlined that capping them does close them out of any possible wins. How many decks can still win if you rip out their breach and their thoracle (still have one left)? It seems like most decks that I'm familiar with are commander + compact plan A + sometimes a compact plan B + "the rest" (ramp, draw, tutor, interaction, etc.).

Argument against would be it's BBB to "kill" one person when you have three opponents. Also BBB would be too slow versus dedicated turbo in many situations. Finally you can't really cap more than one person at a time so there's a large risk of getting it wrong. On the other hand, it's not impossible to recur or \[\[fork\]\] a sorcery so I guess it still warrants at least a thought experiment. It could also create some weird situations where a capped player has to play for a draw so they may be amenable to political deals they'd never otherwise accept.

So I'm asking...are CEDH decks optimized enough where capping is viable?
