So, when I first got good at this game, I decided to try blessed vampires. And while I'm certain I wasn't the first, I certainly credit myself as somewhat a pioneer of the concept. But ever since the antimatter card, I've found my deck to have a fatal flaw I cannot get around. This flaw is a lack of counter spells. Using this lack of counter spells, I've had several ideas for weird decks, but haven't been playing enough to make it work. Ideas:
Scorch deck. Leveled up fire eaters and lots of pillars, devourers and life drains, fireballs, and maybe some of that explosive gas stuff. I can't say I'm an expert on the cards. The only flaw is fighting against extra health enemies like gods, and you can't scorch enemies to death. A lack of healing is also a shortcoming.
Mill deck. By combining malignant cells and eternity, you should be able to last forever without decking out. If there were someway to kill your own creatures and add bonewall, you'd be peachy, but as I don't see any way to do that, and neither time nor darkness have heals, this deck too fails. Perhaps delays would help... antimatter would also be good if you go full rainbow.
Would add more but parents are annoying, gotta go.
