I get the feeling SCG is a subscriber, and bumps prices accordingly. Not saying you're in cahoots or anything, but it seems like EVERY time there's an article with strong praise, they bump prices very shortly afterwards (too quickly to be in reaction to increased demand from QSers). You should test this with praise for something REALLY janky, lol.

I should clarify, I meant across all formats, not just Standard. I can see this being the nuts in some sort of Storm build with Past in Flames (replacing Ad Nauseam), moreso in Legacy/Vintage than Modern (since we don't have access to Rite of Flame and some of the other Rituals and fast mana) and perhaps being used in Belcher as well. Then again, this could be the Miracle card Wizards was talking about preemptively banning at PAX. It is a draw 7 after all.

I'm not sure yet. It's a very difficult card to evaluate, which is the problem. I assume it fits best into a Burn deck or a Graveyard deck, but Burning Vengeance hasn't been a thing up until now.
The fact that it's a hard card to figure means it likely won't find a home until a few weeks in, if ever, meaning there will be plenty available if it does make a jump.

Yeah, world seems to be catching on slowly. My prices are all from Wednesday.

Thanks for pointing this out. I actually missed this. That probably means $5 is the ceiling for a while, though I still expect this to be extremely hot in the first few weeks.
