In my use of Chandelure, I've found that Cleffa is amazing. I mean yes, in general Cleffa is amazing, but even better in Chandelure. If you're just running straight Chandelure, you're most likely using something along the lines of;
4-2-4 Chandelure (Give or take for any of these)
3-3 Dodrio (Give or take)
With this, Mulligan rate is insanely high. Add in 2-3 cleffa's, and it's not so bad.
"Oh, but thats an easy prize for my opponent". Twins. Nuff said.
