In the wake of Extended's major overhaul, I have been contemplating about the rumored new format. I have also been thinking if one day, you wake up and find that Legacy has undergone drastic change.

Picture this: its August 20. You are checking the Source and you saw a thread titled: Legacy is dead. The opening thread reads:

I know a lot of us will start crying and announce our retirement from the format. But for those who will not quit the game, how will this affect the format? Yes, dual lands would be the most obvious. Will this change actually change the whole Legacy metagame? Which decks will see the most change? Will the overall established decklists be changed?

Discuss.
