I used in tournament in very fast rules, event challange, and it help me to finish my 1st Trail of Shadow at stage 3.
EDIT: I was using Cho-chin at 1st try, but it does not work, and after switched Gill-Ra, surprise it works.
EDIT2: back to topic, I love I get Tyrum costume, and I would like to level after Merlin maxed. Fast mana cleanser is great I think and I will use it in war
