For blue I was going to select Jace2.0.
The PW selection box recognized my swipe as a section and it chose Jace1.0 which can’t win these gold tier matches!
Is there any way I can change my PW? Otherwise I’m competing on only two nodes 
Nevermind. It’s over already?
Okay, well if this happens in the future, what would you do?
I wouldn’t expect support to do anything about this scenario.
They’ll most likely tell you to select slow and carefully in the future.
So just slow those guns down!
Make a post in the suggestion forums for a confirmation of selection.
It’ll get ignored but it’s really a feature that should be there, to prevent exactly this scenario.
I’ve accidentally purchased planeswalkers (I mean, Koth is pretty great, but I didn’t need him at the time…) because of this.
