Milotic is such BS
Yeah, it's purely RNG based. Tried it once, saw that I needed to get Feebas. Caught Feebas and then beat and caught Milotic on my first retry. Then I attempted the stage 3 more times because I wanted to S rank it but I couldn't even clear it because my Feebas refused to spawn at the top so I always ran out of moves and the board reset to the default position.
