Fortunately, I (Luis) will be up front answering questions and ringing folks up. You don't want me wrapping your gifts! Occassionally my attempts at wrapping involve copious amounts of tape and not enough paper...

Lauren's wrapping will not disappoint!

We Are Not Buying Cards This Weekend

Due to our anticipated amount of retail this weekend, we will not be purchasing Magic cards this holiday weekend.

Ugin, the Spirit Dragon

We're getting really excited about our new Standard League. It's starts Tuesday!

Questions, Questions that Need Answering

The most frequent question we have been getting is:
What if I can't make every session?

Don't worry! You can have a substitute play for you that week and have it still count toward your league totals. We'd love it if you can make every session, but we understand that your schedule is busy!

Check out our FAQ!

Weekly Mythic Prize

Ugin, the Spirit Dragon

We've decided to go big and award Ugin, the Spirit Dragon to anyone who goes undefeated in any week!

If you can run the table and go undefeated throughout the whole ROUND ROBIN portion of the League, we'll award a Promo, Ugin, the Spirit Dragon to you!

Promo Ugin, the Spirit Dragon

Team Building

While we expect this League to be very competitive, we are also all working together. The round robin portion of the League will cover 120 matches, and we'll have a ton of data to look at. By virtue of playing in this event, you'll be pooling a lot of collective effort that we can use to aggregate and learn more about this Standard environment.

I will be judging these events and look forward to observing matches. After sessions are done, I will be talking to everyone about lines of play, card choices and matchups you've been facing.

If your goal is to get better at Magic, I sincerely believe that, every person entering this League will have learned something new when it's all said and done!

See you on Tuesday!
