Hey, newcomer to competitive here! I've been recently getting back into collecting the cards, which got me interested in starting to play competitive. I've never tried to make a competitive deck before, so I figured this would be the place to get some help. With burning shadows becoming legal soon, I was thinking of using a deck based around sevipers ability to increase poison damage, and crobat 4 damage counter poison attack. I'm not really sure what cards to use, besides what I've seen for some of the new possible standard cards (N, Sycamore, Etc.) and possibly the new toxicroak card as well. Any tips would be appreciated, and anything that could help me learn more about the game would be great.
