I see, so you did not card the other one, thought you had Ent Card on it so you didnt want to use it anymore. In that case, it would have been a good idea selling it to me. I prefer Ent Card over Amdarais Card, for the reasons already explained above. I think Amdarais outshines Ent Card even if you have only 1k raw matk, it will be nice to see you testing the damage increase with Ent vs Amdarais though.
With that much raw MATK amdarais should outperform entweihen easily right
