Vehicles are disturbingly efficient, resilient and versatile yes. Mardu vehicles is still the top dog. You just have to deal with it until and if wizards does something about them.
I dont know how those fog decks and such can win against properly but maybe I'm missing something.
If you want to beat them maindeck reclamation sages. Multiple of the top 8 decks last tourney ran multiple rec sages and that made difference
Because they can't damage you and you either just mill them out too fast or kill them in 1 shot with a flinged drake.(depending on the build)
I don't see how you lose to them the only real "burn" most of them run is disintigration which does next to nothing against you.
I've lost 1 game to vehicles while on turbo fog/eflingma drake and that was on a mull to 5 on the draw while they had their nut hand.
But yeah rec sage is good, creeping mold is good too if you're a mono green ramp deck(both can be played)
i've had them rage quit t3 creeping molding a land and mana screwing them lol.(works better vs the mardu version than rw
Vehicles has a really fast clock, easily killing you on t5 with an average draw. Having to chain so many fogs, while having the tutelage deployed and having enough card draw to sustain, so early is not super easy. They also play Balista and cut/ribbons for some extra reach and have walkers like nahiri and chandra to put you in a very weird position
Between tutelage, fevered visions bounty(some lists) and all the draw spells you play with tutelage it's really not hard to fog every turn, also pulse makes it so you don't need to fog every turn early on.
I have yet to see a vehicles deck play cut//ribbons, normally just push, dec, anguish, skywhalers, harnessed etc.
as for the walkers, you end up playing pulse which can normally kill you out of range of dying to chandra.
Nahiri isn't really an issue unless they have the 1x ula(but i have NEVER had vehicles drop nahiri on me, lilly, gid or chandra)
i'm sure there are some different lists out there but ribbons is at it's best in jund or a control deck.
Balista doesn't tend to be too scary, a point or two of damage here or there isn't anything to really fret over most games.
(don't get me wrong, i'm sure on the draw against a nut hand could very well beat fog, I have just only faced their nut draw vs fog with me being on the play. so i'm not sure how bad that really is.)
I have put in over 100 games now strictly on fog varients and superfriends and vehicles are honestly an match up, hell i've won through tamiyo ults and the jace ult that counters the first spell cast each turn
