It has been a while since the spring update, and with the change of dark pact from 1 blade to 2 the treasure card has yet to be updated.
If this is intentional that is fine, just update the TC text to reflect only 1 blade. But currently the text says 2 blades at 35% and only ever puts 1 blade on the character.
Yes, I am having the same problem. Especially since I was looking forward to casting them in the DECKATHALON, taking the damage since I figured it was worth it. Only to find 1 blade was placed. So it ruined strategy, I lost the match, & bye bye credit. Kingisle what's going on???
