I think I did this math right?
Real odds would be a little lower than this because this is assuming that you also always have an appropriate land. So if you just want to run this out incidentally and don't do anything in particular to enable it it's fairly (but not incredibly) low odds, but you can also raise it pretty significantly if you're willing to run some extra suboptimal mana sources and/or try to mull into it.
It depends on the assumptions that you are making.
Its roughly a 10% chance to open with any given card in your deck. If you have 4 fast mana sources (2 mox, 2 lotus) and 4 Lavinia, its ~15%.
@evouga This card makes me want to learn when SBAs are checked.
On another note, what deck wants this effect? Landstill? I can’t imagine even control decks caring about this more than e.g. Stony Silence for paradoxical/shops. And I think that unlike most 2-drops, this is not castable turn-1 almost ever, and that that makes it significantly worse than Chalice against moxen.
It seems to me this card is at its best against Survival when compared to other hate cards.
Something doesn't seem quite right: the probability of T1 Lavinia with S mana sources in the deck (again, assuming every hand contains at least one land) is
1 - [(# hands with no mana sources) + (#hands with no Lavinia) - (# of hands with no mana source and no Lavinia] / (total hands).
Hands with no mana sources: (60-S)c7
Hands with no Lavinia: 56c7
Hands with no Lavinia and no mana sources: (56-S)c7
Total hands: 60c7
and for S=3 I get 11.4%, not 12.6%.
@evouga Entirely possible--the odds of me doing the math wrong are higher than the odds of playing Lavinia turn one for sure. I just used Excel's HYPGEOM.DIST function and I can't see where I went wrong, but it's quite plausible that's it's somewhere.

This think is going to exhaserbate the mental misstep problem to new level.
I am not familiar with this problem, but I’m pretty sure people were only casting Dark Ritual when they had a land in play anyway 
Best answers for this card are bolt, plow, fatal push, and likely abrupt decay.
Really? I would rank Pyroblast a tier above all of those personally.

@brass-man The thing that makes it hard to evaluate is that this card is easily maindeckable. Just like Deathrite rendered GY strategies much worse in Legacy not because it was the best hoser, but because it was a 4-of everywhere G1.
Against Shops and Xerox this is at it's worst, but even against them it has applications, specially if you land it very early. As I said before, you'll probably side them out on the draw against Shops, for example, but there are good reasons to leave them in on the play - just being able to get to your turn 2 knowing there is not going to be a Sphere or Rod in play is awesome.
I’m inexperienced building Vintage decks. Would you please explain to me how this is maindeckable? Pitchable to FoW I get. But it’s a sorcery that doesn’t appear to me to prevent any opponent from executing 90% of their gameplan.
Bob-Jace control plays Leovold, and Grixis Thieves plays Notion Thief, but this card appears nowhere near as strong as those to me. Am I wrong?
@evouga I believe this is correct, but then for the truly exact percentage you also have to factor in lands that produce W or U since that will drop it and there are simple additions, like adding 1 lotus petal, which boosts the number to 14.5%. So I think in total saying a rough 10-15% is accurate.
Its a little more complicated, but what was the probability of playing turn 1 Lodestone? Because I'm fairly certain it was roughly around the same as this at 10-15%.
You can also cast a turn one time walk via an off colored mox to get you to 2 lands.
@john-cox fair. I would say that this guy is still marvelously insane on turn 2. Don't get me wrong everyone. I will be testing the crap out of this guy

You got me

That looks to me about the same as the odds of dredge failing to find Bazaar, no?
11.99% is the chance of having a "one of" in your opening hand (say ancestral).

Leovold and Notion Thief are both way harder to cast than Lavinia though. If any of those cost only 2 colored mana, sure.
Lavinia gets in the way of a lot of stuff. Moxen, counters, PWs. It can even act as Defense Grid in a way. It's maindeckable because we're theorycrafting a 4 Lavinia deck that uses the tempo advantage she generates to win quickly or to get an unsurmountable advantage quickly.
I wonder how she fares paired up with stuff like Armageddon or Fastbond + Crucible or Balance 
(probably bad, but this is the fun stuff we should always try out). Also, if we ever have a Lavinia-meta, Gush can come out of the restricted list easily hahaha

The MM problem is the one people refer to when they constantly bring this card up as being restrictable. It is a super powerful card that limits deckbuilding space to a crazy degree since literally any deck can run it. This is the same problem that got the card banned in other formats.
Pyroblast works, but then also suffers the same issues as the other removal once your target is in play. If fighting on the stack you have to win a counter war and it assumes cavern was not used.
I've just consulted the comp rules, and it seems a little uncivilized... but if I'm understanding correctly, you can actually just pay mana for phyrexian costs.
