Not clear on this.
I use my Anima's "Surge" ability during the "Standoff" phase, and "deactivate" 3 cards from my hand.
Lets say I had no cards in the deactivation pile initially.
When do I put these deactivated cards back into my hand?
At the beginning of THIS rounds "Activation" phase, or do I wait till the NEXT round?
I'm thinking NEXT round.
Next round. Check out the errata/2nd edition rulebook I posted, it clears this up considerably!
