I appreciate the response. I went a little bit off on a limb asking how much better the Night March cards themselves are against Yveltal cards, without a lot of knowledge about the subject, and I’m glad you brought up Joltik + Silver Bangle as I wasn’t aware of that interaction. 3 Night Marches could easily be set up with one Compressor, so a combo like Compressor + Joltik + Bangle + DCE = Knockout Yveltal looks pretty lit actually. The only issue I’d raise with bangle is not having as many interactions with the rest of the deck because of it having to work with non-EX Pokemon.
As for the Eeveelutions deck, I’m not as worried about making it work on a technical play level (I have way too much free time to take care of shit like that,) but it just not being that good would certainly be my first concern with switching over. Ultimately though, the most recurring problem I’ve been having with this deck is beating Seismitoad at all. I would think that even with Leafeon, it would still be an uphill battle at least. I’m the last person on earth that would advocate using anecdotal evidence to promote theory (with little information to work with right now it’s all I have,) I’ve found the only games I’m winning either are them bricking, or me going second and quickly establishing K.O trains.
Last note, I’m sure this has been brought up before, but I’ve also found Lysandre’s Trump Card to be the easiest thing to play around in the world, and only matters if they Seismitoad you in the same turn. It’s just too easy to keep an extra Juniper around or excess Compressors, and being able to use a low-risk technical play aspect to beat what would otherwise be a great thread to the deck for free is amazing.
