You have a great stream, Andreas. Have been enjoying watching you.

Vintage leagues are live on MTGO as of right now.

Starting with this set, all planeswalkers past, present, and future will have the supertype legendary. They will also be subject to the "legend rule." The "planeswalker uniqueness rule" is going away. What does this mean? In short, everything that's true about legendary creatures will now be true about legendary planeswalkers.

So you could have a Jace, The Mind Sculptor, and a Jace, Telepath Unbound in play at the same time. This seems legitimately Vintage-changing to me.

What @ChubbyRain is saying here is very real. Recently I've lost games against Shops where turn 2 Tinker Blightsteel was not nearly enough to avoid dying.

I'm not sure that you can afford to run 2 Delve spells without 4x Preordain and/or Dack Fayden. You just won't fill your graveyard fast enough.

I think you should slot in at least one Snapcaster Mage, too, because it's just too good with Flash after your first one gets countered.

I took great joy in being able to provide @Solemn_Storm with an actual copy of Caustic Caterpillar for his NYSE sideboard, replacing the proxy he had made.

@The-Atog-Lord said in Vintage Challenge - 7/8/2017:

But an Atog just did. The Gifts deck is good.

Until tonight, I had never seen an Atog Manamorphose before.

@p3temangus Haha, I was thinking about both Confluence and Sylvan! And yeah, I took Crucible out of the 75 without thinking about that upside...

In my recent games with this deck, I've often felt as if I've had good cards in hand, but been unable to cast them. It hasn't been immediately clear if this was just bad luck, or bad mulligan decisions, or 3 DRS not being quite enough. Anyway I'm now trying a build with 4 DRS.
