scheme

Im thinking of putting a really long article for seo up on my blog with the text being the same color as the background leaving only my opt in showing. Will this work or be a waste of time?

I was design this link building scheme with pentagon style involving 8 blog, so what do you think? one way link in cycle method. i think it's better use defferent IP and same niche to this scheme. look natural to google, A->B, A->D, etc. any other idea please share! :D
