EDHLAB Patches

Gameplay Update 10/22/26

The dev team has been busy behind the scenes and have some major changes, aesthetic improvements, and new features to share.

Does your commander need their trusty Ikorian sidekick by their side? Do you want to see what decks people are playing from outside the lobby so you can judge them mercilessly before joining up? Do you love playing aggro but hate doing combat damage math? Take a look below at everything new on EDHLAB.

Combat Damage Auto-Calculation

As any Commander player knows, keeping an accurate account of combat, especially when it comes to declaring attackers and assigning blockers, is a difficult task. Fortunately, the miracle of technology has made this a cinch. In today's update, we've added a brand new feature: combat damage auto-calculation.

Not only does this feature add up and display the total power of creatures attacking a player, but it also dynamically adjusts the total amount of damage once blockers are declared. Now you'll never lose track of how many Craterhoof'd Elves are barreling towards you!

Companions

Get those Lurrus Reanimator lists ready, because EDHLAB now officially supports companions as part of your Commander deck. You can import a decklist from your preferred deckbuilding website that includes a companion, or set an appropriate card in your sideboard as a companion in the Deck screen.

Sideboard

You heard me correctly! EDHLAB now offers official sideboard capabilities in the Deck page. Though the Commander format does not legally allow a sideboard, this feature allows you to keep a list of potential cards close by if you find that Counterspell just isn't cutting it in your Multiplayer games.

Simply click on a card shown in your sideboard and use "Move to Main Deck" to add the card to your 99. Just don't forget to swap a different card out.

Feel free to get creative with your sideboards however you wish, and keep your eyes peeled for some more ways to use it in the future!

Aesthetic Updates

We've also made some cosmetic changes so that the EDHLAB experience always looks great.

If you're a superstitious lobby host, you've probably grown tired of mashing the Shuffle Players button. I have good news for you; player shuffling looks nicer. Lobby hosts can rest easy knowing the shuffle feels and looks much fairer.

Clicking to update your life total needs no guesswork with the new dynamic life change feature. This animation plays when changing your life by clicking the buttons, using hotkeys, or even typing in a new life total. Combined with auto-calculation, life totals have never been easier to manage!

Do you like to peruse the commanders others are playing? The new Multiplayer lobby panel gives you another way to do so. Find out what commanders are hot on EDHLAB or avoid the menacing Grand Arbiter Augustin IV waiting for victims in an open lobby.
