I’ve found that instead of focusing on the claim, focus on the actual effort the author is putting forth and what you can learn from it. I wouldn’t even worry about the stats from Jordan’s testing, nice as they are, but really read the details of those test games. Count the times that Day’s made a difference, make note of when the opponent thwarted it, or even took advantage of it. Use his information to prepare yourself to use/face Day’s. Study the interactions, because those are what help improve both our understanding of the card and our skills as a player.

Your reply is nice and pretty well reasoned, and its true. Card evaluation is very tricky, and you are right that it is pretty early to draw conclusions.

A few things on this. For one, it’s way too early to draw format-wide conclusions about Origins. Although some cards slotted into decks pretty easily (Harbinger), others have heavier deckbuilding requirements. We’ll need more events and data to know how those cards do. With Undoing already seeing early success in Legacy Affinity (6th at SCG Chicago), it’s only a matter of time before it makes its way to Modern.

As for card evaluation, every site has hits and misses with new cards. For instance, authors on both SCG and CF gave Narset, Transcendent glowing reviews, but she’s fallen flat across the board. Similarly, many sites didn’t quite appreciate Kolaghan’s Command when it was first spoiled, despite its later success. We can’t promise a 100% evaluation average. We can, however, promise thoughtful, well-reasoned, and supported claims, which is what Jordan made in his Undoing articles.

Overall, we’ll need to wait and see how the metagame adjusts to the new Origins cards!

That said, I do think that Pia and Kiran Nalaar’s absence from these early decks is the sign of something greater – it’s been unable to dislodge Huntmaster of the Fells from Jund decks, and I don’t think they ever will (it’s not like that card was an ironclad part of the core). I also worry about Languish -4 power may be suppressing Abzan’s offense on that turn to the point that they don’t actually want to play it, despite it being a selective sweeper in many cases.

Hangarback Walker strikes me as being a bit too much of a slower value-type play to truly be a transformative force in Affinity, but it might be worth it as a 1- or 2-of. I don’t really like playing Spellskite mainboard in a primarily aggro deck anyway, and that makes for a decent “2-drop” and Modular counter repository.

I expect we will see more Day’s Undoing in the weeks to come. Without the pressures of a GP or PT on the horizon, there isn’t a lot of urgency to Modern innovation right now. So it will take a little time for players to figure out the best way to use the powerful Undoing effect.

Of course! We will need lots more data to know for sure. But with the first Origins results now on our radar, we definitely want to check in and see how cards are doing. We’ll keep adding more results to this and check back in as the format keeps evolving.
