Sweet brew! Eldrazi are what got me excited about playing constructed. Sucks that you feel priced out of standard. I played nothing but drafts and pre-releases for a while for that reason, then ended up opening 2 Gideon's and being able to build something decent for Standard. I got back into the game during khans block standard, and it was as pricey as Modern for a while. If you wanted to get back into the format, now's a great time. All of the legal sets have been printed into oblivion on account of Masterpieces, so cost of entry is pretty low unless your local meta is full of tier 1 grinder netdecks.
