@busoftheundead I think black has an insane amount of creature removal. What you just proved to me is the fact that you cannot get through the counter spells. Toxic Deluge and Liliana of the Veil remove some many creatures in addition to diabolical edict or an old fashioned Terminate. A lot of people are playing Kolaghan’s Command for extra removal. Kevin Cron played that against me when I was Oath and took me down. There is also Abrupt Decay and Malstrom Pulse and Pernious Deed which are all fantastic against Oath.
I played Dark Times when could be played in Vintage and the issue there is Mental Misstep stop discard and Defense Grid will not protect and combo where you win with a creature beat down.
