The Mercurial Heart season is here, and there are a couple of changes that you should be aware of if you’re trying to play the game competitively. There are new sideboarding rules, and the ban list has been updated. 

If you haven’t picked up any Mercurial Heart, always support your LGS, but you can pick some up on TCG Player through my affiliate links. If you enjoy these updates, please leave a like, comment, and share this with your friends. Don’t forget to follow the socials!

Changes to the Sideboard

Players are now allowed to have 15 cards in their deck as opposed the eight previously allowed. Please note that material deck cards such as Champion and Regalia take up three slots in this new system. That means that the sideboard can be made up of 5 material deck cards and 0 main deck cards, 0 material deck cards and 15 main deck cards, or a combination of the two.

Ban and Restricted List Update

Banned

There are no new bans this month, but keep in mind that following remain banned:

Category 2

Erupting Rhapsody has been moved up a category to the watch list. This means you should probably start making your decks without it in your decks because it is heading towards the chopping block.

Category 1

Chalice of blood has been added to the category 1 watch list. Category 1 is for the cards that the devs are watching as problematic, but there is no danger of a immanent ban. You can fill your decks with the following, but be mindful that a ban might come some day.

You can read the reasons for the changes on the official post.
