I know Swarmyards would double/triple your budget, but they would be soo good!

This is a great suggestion! If i ever happen to stumble upon some cheap copies, i'll include them. Thanks a lot!

If you're worried about your early game, try adding an Assault Formation or two, as well as more 2 mana spiders . A 3 mana Sporecap Spider can become a 5/5, and the Juvenile Gloomwidow is particularly devastating with it's wither effect. Also mentioned in previous comments; while Swarmyards may be pricey, they're a game changer for this type of deck. Pretty solid overall though, I like your choices of removal.

ChocolatePuma: thank you for the upvote and the comment :) i really like your suggestions and will try to include them. Ideas for what to replace?

Possibly only run one of each of your beefier spiders like Ishkanah, Grafwidow and Arachnus Spinner? From my experience they're mid to late game creatures so it might be unlikely that you'll get to play 2 of them if your opponent has any effective removal.

ChocolatePuma: i don't like that idea too much. Ishkanah is kind of my wincon, and the spinner is too important. I'm pretty unsure about the Nyx Weaver here. Maybe i'll try dropping her. But i'll keep your way in the back of my mind. Thanks again :)

Hello, in my opinion, i would put arachnogenesis, metallic mimic, some effects to grow power of creatures like gaea's anthem, adaptive automaton, and i don't like very much arachnus spinner
