Hi,

Thank you for your comment.

If I were to classify High Battle Start Proc Rates AOE SR Cards like Spade, I won't consider her as a choice for Mirror Maiden.

These days, it's common to at least encounter a few Defense that has LRs/HLR/GLR cards in them and cards like Spade cant really deal with these Defense teams in one turn, thus they don't really contribute much to an ABB Attack Teams depsite their high proc rate. It will be a different story if she does some Turn Skipping though.

High Battle Start Proc Rates Turn Skip SR Cards like Queen Succubus, she's much better than Spade since if she procs, you get 3 turns for your other 4 cards to do something meanwhile(More AOEs, More Turn Skips). I will consider her under  C. Alternative Choices

Basically, the rating depends a lot on the Card's Skill and Rarity.
