>>43393155It's situational even in doubles.
You need to be using one of the few mons with access to Rototiller, be using a grass-type, preferably have the opponent not be using a grass-type, and for what?
All you get is a +1 to attack and special attack, which can be accomplished by having the grass-type use growth, which is a common move for grass-types to have.
If it was a +2 to both stats, or even an omniboost, I could see the benefit of going out of your way to use it, but is it really worth wasting a moveslot as it stands?
