This entry is part 477 of 542 in the series CommanderCast

Hello everyone and welcome to CommanderCast Episode 439! This week Mark and Adam are copying each other’s homework with the new Commander 2021 exclusive mechanic, Demonstrate. This new mechanic allows a player who cast a spell to gain an extra copy of it, but only if they allow another player to also have a copy of it! This could lead to some very interesting game states. But first, what is new with the Secret Lairs turn WotC? The guys want to go over some of the recent developments involving this product. Then they wrap things up with a tech segment around Magic’s most tech based card type, Artifacts!


All that, plus our usual interstitial fodder, and all you have to do is Click the IB!!!

“Demonstrate allows players to copy a spell when they cast it by allowing an opponent to have a copy as well.”


Demonstrate cards:


The mechanic is the cycle; the cycle is the mechanic…
