@john-cox Incidentally, I went to MTGGoldfish to look up Cryptic Serpent and a couple RUG delver lists played it as a 1 of. Kind of makes sense, as it preserves the graveyard for Nimble Mongoose and Tarmogoyf. Salamander Drake would likely be better due to evasion, but this is another potential shell for the card, and situation where one would look to Salamander Drake over cards like Gurmag Angler.
Didn't take long for a 5-0 in Legacy. I remain skeptical in Vintage but seeing it in the Arclight Phoenix shell raises the possibility for modern. I doubt it's better than other options, though.
Also, someone should probably fix the Thread title so that it has the right card name @Brass-Man
@ChubbyRain I think in the right meta it could work in Vintage. I think it truly depends on if people are willing to try new, wild things. I would be very excited and happy to try and brew a Phoenix list with this for Vintage, though this card may be the worst card in the deck. I think it could perhaps be good certain slower metas with say Jeskai Control, but I also think that this is good as yet another blue threat for U/R/x decks to close out the game with.
@rat3de I tried Phoenix. It was honestly too slow against Survival and PO and too difficult to trigger against Shops and Eldrazi. Oh, also go blown out by Containment Priest, and unlike other similar effects, the ability is not optional. That deck became the UR Thing in the Ice deck I played a couple of months back. I think I did get a 4-1 on stream with the Phoenix. It just felt like a much worse version of similar URx decks. And I think that's where Pteramander ends up.
@ChubbyRain Interesting. Do you have a link to that stream? I would be very interested in watching it. I still think that Pteramander has potential in a slower meta, but I would be happy to be presented evidence to the contrary. I do not think this is said enough, but thank you for all the work you do for the Vintage community through your data collection, streams and sweet brews. It means a lot to some of us, and I am hoping @RandyBuehler will invite you to the VSL soon.
