@chubbyrain Satisfying a curious itch: guess it's like 12% with 4 Lavinia, 16 lands, and 1 each: Pearl, Sapphire, Petal, and Lotus.
Assuming only 12 of those lands can actually produce U/W: 10%
Disclaimer: all real math lazily disregarded for programmatic sampling.
@fsecco Weirdly enough, I think modern Workshops' aggro focus probably makes the ability pretty lackluster for stabilization once you get to six. Specifically: it's worth noting that the +1/+1 counters from Ballistae, Walkers, Ravagers, and Overseers stick around.
For a significant chunk of the creature package, this ability reads: Up to two target creatures get +0/+3 and lose all activated abilities. Not nothing, but might actually be more interesting in the more-controlling, unrestricted Lodestone meta.
Having been on the other side of this in a previous P9 challenge, I must admit it was originally somewhat disheartening to watch the replay and discover that I was facing down 2 players, plus a third over Skype.
That said, I know that I personally got a lot out of being able to re-watch that match from my opponent's point of view; to hear the considerations of his lines, see what he had, and especially to hear the debate between different lines. It was a wealth of valuable information that you just cannot get anywhere else. I was able to easily pick out my (very) loose plays, see where I had my windows, and when they closed. I lost the match, but was able to get a heck of a return on that loss.
My two cents: I definitely wouldn't want to see an end to the way that Vintage has been streamed recently -- the community, entertainment and educational value provided is far and away worth more than the occasional feelbads.
