The main reason this time is honestly, I need a break. I've been running this for 6 straight months. (Save the 2 weeks I was on vacation, and the one week I took a break.)
My level of caring has dropped from excitement to tedium. As such I'm getting tapped out for new ideas because I find myself having a lackluster attitude about the tournaments and I don't feel I'm giving you the challenge levels you deserve.
They will return, I just don't know when. There's a lot of factors involved some of which will be announced at a later date. I'll still be running the rare updates lists so that when they do return, we'll have a fresh batch of rares.
I am sorry guys (and girls). I just need some time off.
Thanks for doing it all these weeks. It was something the English speaking community realy enjoyed and appreciated. Inspired lots of really interesting "how the heck can I make a deck to play in this!?" threads in our guild, at least.
