So here’s what we know about upcoming update from devs stream:
Stack will now be a lot faster. It was set to 1 second and is now .4. For anyone not familiar with the stack, think of situations like polyraptor and having a ton of triggers that you have to press ok on. This should now be faster.
Popping treasures is a lot faster, making it easier to do 1000 year storm and anything regarding treasures!
Deck building now lets you sort by set by just clicking on the set. No longer have to type it in like now.
In BO3 the player that wins the coin toss can now choose to play first or last. From what I gather this is only BO3 format.
There is going to be a singleton metagame challenge mode coming out. No details on prizes, but should be similar to the constructed one.
There will be a Guilds of Ravnica Constructed event (can only make a deck with Guilds cards)
Sealed is coming back and M19 is the first one! If you have pre-release codes and didn’t use them they will still work (1 per account, so if you used it for Guilds then you cannot use it for DOM).
