About the shield: if you also had a sanctuary out the shield can't work because sanc prevents the change of your quanta pool in the enemies turn.

That nearly killed me in the last match in the Plat Arena! Mindfactoried me ~32 QT so I had 75 each and got me that shard and used the shield it gave me (feeling like a boss then) ....

...boy was I glad when I was able to put a Dim shield out again!

Edit: Just realized..sorry for the OT! So I will write down an answer so nobody gets mad at me:
Just because an update forces you to change your tactics you did not waste your time, you just have to learn new. And since this can happen to you in any game I strongly suggest you learn to accept it or maybe search something else to do with your time.
Marsu seems to be in a good mood, I would give you 1/10 only for trying.
