Why ban Nymphs? Unless you view them as a form of mass CC. Perhaps ban Blue Nymph, especially since no mirror shields
Why ban Fractal but not Mitosis?
I understand banning bolts, should be mentioned
Why ban Graboid but not Fate Egg or creatures with ablaze or growth or Lycanthrope or Mutation or Rage Potion Mercenaries? Consider if graboids would really overwhelm the meta in the face of Blessed Dive, Aflatoxin against no shields or mass CC (though no Empathic), Purify+Heal+Adrena vamps, Purify+Heal+Adrena Pufferfish
Purify not banned. 6 Purifies heal 12 per turn. I suppose needed given the strength of Poison otherwise, unless you ban poison cards alongside Purify
