@revengeanceful I'm not totally up to date with what a mana ability is anymore but no you should not be able to counter a lotus or moxen or sol ring with this because they do not use the stack, they just instantly resolve so long as there are no targets on the mana ability.
The things that it does counter that are pretty interesting are Oath, Survival, Time Vault, Voltaic Key, a bunch of the Tormods Crypt analogues. I believe it can also kill Urza's saga as soon as they play it and trigger the lore counter being added to it, before they can even squeeze it for mana.
@babau Maybe? Previous cards that tried to stop Storm by being painful still let the Storm player go off and so they were far less powerful than cards that STOPPED the Storm player. At least this one guarantees lethal damage before the Storm count gets to 9. As turn 1 off a Workshop, I could see it if you needed a narrow answer to Storm.
@thewhitedragon69 You are absolutely correctly, that this is just is. My point here was something that @Smmenen brought up in their last podcast. Vintage has always been a format that exploits fast and free spells. My point about MH1 and MH2 is that we got a lot more "free" spells and many more fast spells that have really locked the format into it's arch types.
I'm not making a judgement, more of a statement about format identity.
@serracollector It's a house in Standard, but I think Traxos just does what this wants to do but better. Yes, this has ward 2, but it doesn't have trample or "vigilance", requires 6 artifacts cast to be the same power of Traxos, and a Force of Vigor really still handles both since getting 2 mana available behind a FoV is small fries in Vintage.
One way to do this (assuming no one already has) would be to make a bot to record play draw and winners and throw it as some of the streamers YouTube vids. This would yield a fairly large data set relative to the rather small vintage community although it would have a number of unfortunate confounding factors.
