Holy crap just reading through the parch notes is exhausting, thank you for doing all this work! There is a lot of complaining here, and that's fine, but I'd just like to take a minute to appreciate all of the things that are working in this incredibly complex game.
External link →Did you know you can attack with a whole stack of creatures by clicking on the count? Based on the incredibly small number of reports we got when this stopped working if your opponent had a Planeswalker out, the answer is no, you did not know that. Well, you can, and now it works in all scenarios.
Definitely the best thing I read in here. I didn't know this, plus it's great it works.
You can also block this way - If you have a stack of 1/1s you can click the stack counter to assign the whole stack as blockers
