Change is a-comin’. The so-called “London Mulligan” is an experimental new mulligan rule that will be tested at the Mythic Championship, April 26-28. The last time they did this, we wound up with the scry mulligan, which has honestly been pretty sweet. So will this new rule build upon the success of the scry mulligan? Or will it plunge Magic into anarchy and irrevocably destroy the game forever? (Hint: not the second one.)
