What about adding Door of Destiny? Perfect for a spider tribal deck.

I actually just took Door of Destinies out a few days ago! wrote about it in the update. I did manage to play it quite a bit but every time I managed to make it big enough it would get removed, and it's actually slower than you'd think.

Deserted Temple with rings and coffers that tap for 6 or more mana is infinite mana.

Very nice write-up! The deck looks impressive.

You have all these good lands but no overgrown tomb?

Aah, I have a tomb in my other decks, just hadn't really needed it here. But yeah you're right and it should replace one of the slower lands.

i love this deck i thinks its a good brew. and me being a spider and elf player its pretty nice against someone with arachnophobia ;)

Nice list and love the writeup too! I'll definitely borrow a few ideas to my in-progress Ishka-chan deck. Have you considered Dryad Arbor? That's a creature and a land for delirium in one.

Any thought of adding Benefaction of Rhonas to the deck? It seems like it does everything we want.

Dryad Arbor is a good suggestion with it being land and creature type, but I didn't put it in mainly because it's not a spider. Should I ever include non-spider creatures then this will go in definitely yeah.

Benefaction of Rhonas is a nice new card as well, but have to be careful with what you throw in the graveyard as I don't have a lot of recursion. As it is now, getting Delirium is working easy enough, including this would mean you need some more recursion as well.
