This weeks card of the week comes from our Keeper of the tomes.
Let’s set the scene you opponent is attacking you with a Blightsteel Colossus, an unblockable creature and you know a ninjutsu trigger is imminent, perhaps they have played a load of pump spells or they have just turned their board side-wards.
Ending the combat phase will exile all spells and abilities on the stack, this includes spells that can’t be countered. This coupled with the low cost of Mandate of Peace means you can two-for-one or three-for-one your opponent. Mandate of Peace is a card that you can run with minimal downside as at worst it is a fog, that can be used to save yourself or as a political tool to save others.
However, the most important line on Mandate of Peace is “Your opponents can’t cast spells this turn”. They will still be able to cast spells in Main Phase 1 but is a common pattern of play for players who plan on attacking to play a land and go to combat, this allows them to use their Main Phase 2 to continue with their game plan or react to what happened in combat.
