2 questions about Rotom Fan form?

Question

1. If a pokemon with mold breaker uses a ground type move on Rotom fan form, will it hit, or will mold breaker not override levitate and the flying typing?
2. Theoretically, if rotom fan form used roost, would it then be vulnerable to ground type moves for that turn?

I do not require you to answer number 2 but I would like to know.I am aware that rotom fan form can not learn roost legally, I'm just wondering what if.

Answer 1

1.Mold breaker only works for Abilities not types so you still cant hit it.

2.If the rotom used Roost the same turn you used EQ and you had a Mold Breaker pokemon then yes you could hit it,
