Mirror Destiny is a poor spell if your going for high Evasion (High Evasion Builds are only any good for Normal Monsters and PvP) as if the opponent cant hit you then there is nothing to reflect. As the Name of the spell implies Mirror Destiny if you destiny is to dodge then you reflect a dodge. Personally if you know your Evasion I good enough that the opponent isn't going to hit you then just hit them instead lol
Unfortunately this side effect also effects the Rogue Steal spell so again high Evasion makes it less effective if you cant steal attacks cast at you, but you can still steal the opponents self buffs :)
Thinking about it MD is the only real counter to a really high Evasion Build, so if your going for Evasion might want to stick with 2 Slot spells like CV or use insight when casting 3 slot spells.
