Copy of: Caw Blade by Ben Stark (Standard)

Caw Blade started off in life as a deck called "Caw-Go", a play on the classic control gameplay pattern of draw-go. It played Squadron Hawk and Jace, the Mind Sculptor, and was a classic control deck with permission, interaction, sweepers and card draw. Then, once the Scars of Mirrodin block brought powerful Equipment like Batterskull and Sword of Feast and Famine, the deck added Stoneforge Mystic and became Caw Blade.
This deck was so utterly dominant at the time that it drove people away from the game. GP numbers dropped, attendance at tournaments everywhere was affected because people were so sick of this deck. It got to the point that it was 60 percent of the field - as the saying went, you either played Caw-Blade or you lost to Caw-Blade.

Both Jace and Stoneforge Mystic were banned in mid-2011 as a result, and in August of that year they were both grandfathered onto the Modern ban list when it began as a format. Caw-Blade left such a mark in people's minds that Jace and Stoneforge weren't unbanned until 2018 and 2019 respectively, and it remains one of the most infamously powerful decks in Magic's history.
