Ok, so since I get people asking me about Spider 20 more than anything else, I wanted to put together a comprehensive video covering all aspects of it, so that anyone should be able to work their way up to it with their own unique compositions:

There are a few different builds you can make to handle Spider 20, and I cover all of them in this video.  The video is long, but like I said, I wanted it to be comprehensive enough to help anyone with any of the various compositions you can make.  Every person's strategy on Spider 20 is a little different, unless they go full cheese group (which takes at least 3 if not 4 cheese champions like Royal Guard or Coldheart).

Anyway, hope this video helps all of you!  If you have any questions about it or need any help, best place to find me would be post in the comments of the video.
