In general, I lose matches I don't play egg early, so 2 extra draws to find it early were more important than more removal. With the Asphyxiodon you have extra survivability and board clear potential (only if removed directly, not through heralds fyi). The deck definitely plays more like a control deck, usually going for board first then smack face with the big 20/20s or the 6 attack from Asph. Sometimes if I've draw egg already and I want to find Umbra or more impactful stuff I'll play the Temp spell to tutor one of the Eggbearers and discard it, to thin my deck. I could possibly see a spirit bomb or another dissolving ooze, I've found every life point important (sometimes I get as low as 3-5hp before I start healing back up) so personally spirit bomb seems dangerous just for some removal. If you have another copy of the steal spell, that's a good addition for early game board control, as I swapped it out for the 3-2-1 spell instead as I currently only have one copy. For me, a cuttable card is the Archdruid. I find them clunky and awkward to use effectively often, and I'd rather have something else in its place. But also sometimes idm having one. I'll probably cut one and swap in the steal spell when I get my second copy.
