The June 18, 2010 DCI Banned & Restricted List Announcement is a whopper! Extended as we know it is changing dramatically, and Legacy will see some upheaval as well.
Effective July 1, Extended will go from having seven years worth of Magic sets to having four years worth. A whopping eleven (11) sets are rotating out on that date (Ninth Edition, Mirrodin, Darksteel, Fifth Dawn, Champions of Kamigawa, Betrayers of Kamigawa, Saviors of Kamigawa, Ravnica: City of Guilds, Guildpact, Dissension, and Coldsnap.) From that point forward, starting with the release of Scars of Mirrodin, each fall set will cause the oldest block to rotate out. Thus, when Scars releases, Time Spiral, Planar Chaos, Future Sight, and Tenth Edition will rotate out. Goodbye, Tarmogoyf, it was nice knowing ya!
Clearly this decision is intended to shake things up and will hopefully do just that, breathing life into a format that has been on DCI life support for a few seasons now.
However, Mystical Tutor has been banned, which should neuter one of the format’s preeminent combo decks, Ad Nauseam Tendrils (ANT). Losing those four slots universally held by the tutor will be a hard obstacle to overcome, and while the deck will likely still survive in some incarnation, we can breathe a sigh of relief in knowing that the dreaded turn 1 kill will probably happen a lot less often in the format, with only the somewhat-passé LED-based dredge decks now being capable.
This should prove to be among the more influential Banned / Restricted announcements in recent times, and here’s hoping it has the desired effect of making Extended more interesting.
