Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
I like tech options lol. And it seems like forcing rillaboom out rather than letting it blast through your team is a pretty sweet option to have. Personally I hope this moves makes it into consideration
What about Bug as a coverage option? Something like First Impression could force out grass types (minus ferro) into flying types that resist it, and put 31 in a good spot to fire off DS. Libra and Lando are still viable switch ins as well
