Continuing with the leaks I totally loved Cursola :3
Finally Corsola has some love. It's a shame only galarian corsola has it tough, but still. 
Ghost type and incredible sp att and sp def. 

Perish body is a new ability that if the oponent makes direct contact with Cursola,
Perish song activates. Both pokemon have to retreat if they dont want to faint in three turns!

This is why Mareanie is running away from the field. 
I tought Cursola scarying Mareanie away was funny, due to the fact that Mareanie are common predators of noraml Corsola
Who runs from whom now?! xD
