Obviously the metagame is completely different now, it is difficult to make prediction from this.
On Mental Misstep:
Honestly, mental misstep is what keeps the meta interactive. Otherwise we would have players goldfishing on both sides of the table more often than we do now. (Storm doesn't need to be better.)
I like MM keeping restricted cards like ARecall and 1cmc tutors in check outside of them being restricted as well. Unfortunately, MM is necessary with all the 1cmc cantrips in existence at this point.
My 2cents anyway.
Duress effects will not get better with the restriction of MM. Duress effects aren't as good now because we have so much draw available than before.
the decks that run Karn, don't necessarily run MM. So, Duress could be used against them, except Duress has to happen before the taxing effects come down on the other side.
If Narset goes unrestricted and MM gets hit instead, Narset isn't going to be weaker. Duress here won't do much either. Decks running Narset have the big blue draw engine already to stay ahead.
Duress and effects like it, are weaker now, not because of MM but because of the powerful card draw available now. Let's face it, Duress effects are huge tempo loss in most decks now, unless they can win on the spot. (DPS/ANT)
Not only that but we have Collective Brutality available to us, which dodges MM and it's more versatile.
In the case of Dredge, Force of vigor/Negation would be more at fault for its current strength, not Misstep.
Also, Deathrite Shaman is doing just fine in the current meta. Doesn't look like MM is keeping it oppressed.
Oi, this card used to be compared to Mana drain and as such, competed for slots in blue decks. Spell pierce is purely defensive, where MM can be proactive as well.
One of the main reasons Flusterstorm took the spot over pierce was simply because you can be more aggressive with your plan than you otherwise would be if you ran Pierce or other narrow counterspells.
If MM needs to be restricted merely on the grounds that Pierce and Duress is not played anymore/as much, then Flusterstorm should follow suite because it pushed Mana Drain out, as well as suppressing strategies relying on mostly instant and sorceries.
I hope I expressed myself well enough, apologies if I didn't.
I'm a bit under the weather but had to post my thoughts before they're rendered irrelevant by tomorrow's announcement.
@ten-ten I used to agree with you but I think too often now that Mental Misstep is used to aggressively disrupt early game plans by hitting Preordain, Dredge hate, and removal spells. And just so you know, stock Dredge lists aren't running Force of Negation. Force of Vigor is a more significant contributor but likely a net positive for the format.
Regardless, I remember when I started playing that Chalice of the Void was the key card that kept Rituals in check and could never be restricted or it would be "combo winter" or something along those lines. That was proven to be false. R&D is taking risks when it comes to card design. I actually think it's a good thing for the format, though the B&R action needs to keep pace as these cards aren't tested or intended for Vintage play. Why not also take some risks with B&R decisions like restricting Mental Misstep and seeing if the other interactive spells in the format can control Storm enablers. It's a good time given the printing of FoV, FoN, Narset, Karn, Ouphe, Lavinia, Veil of Summer (if you've cast this card against Storm, it's nuts), Dovin, Ashiok, etc. And if it doesn't work, I hope the DCI flips the switch back in 3-6 months.
I wouldn't mind MM, or anything for that matter, being restricted. Except, it's highly unlikely wotc will revert it's decision if MM was the incorrect call.
I think proving a restriction was incorrect months from now would be highly improbable, especially if they hit multiple cards at once and/or unrestrict something. Not to mention new set releases may influence the meta by then.
If MM is restricted, would you guys keep a single MM in aggro-control decks, or none at all? I feel like there are cards that I'd want to run at least two, or none at all, and I'm not sure where MM stands.
You absolutely run it, just to have it for the 1 Ancestral and 1 Sol Ring. If only to dunk the 18 year old math majors who claim Ancestral will ruin Vintage forever without the old stalwart Skillstep holding in check.
