For the shadow splash version of this deck, see: https://eternalwarcry.com/decks/details/j0oa4MRX0XM/purple-wurmhowler-the-evolution-of-crown-roaches. While the shadow splash gives access to some very powerful cards, it sacrifices consistency and speed to somke degree.
I'm currently unsure which version is better and am testing both, feedback on which you prefer would be great!
Edit: Never mind. Tried. Just makes a janky deck even more janky
