Yeah I have to agree with Philippe, the two sides here don't have a very effective relationship together, not enough to justify utilizing both sides at least. If you're wanting to stay in a standard environment I'd definitely pick for one or the other - wizards has potential to do some nasty damage, I'm not entirely convinced in the current standard environment that spiders can be effective right now without intensive support from other elements.
Keep going at it though, if you want spiders then damn well make those spiders work for ya, you'll just have to find the supporting tool to make your web-dreams come true.
