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 love that when a player posts a really obscure set and it gains traction, there is always someone that needs the validation of pretending they used it before...
I honestly think Whirlwind deserves second, if not first, slash. It's such a great tool for a defensive Ho-oh, being able to simply phaze the ones trying to set-up on it for free, as it's not as powerful as the other sets. Racking up hazards damage is also good.
Slash only Roost for consistency; do keep the difference between the two though. nvm that, the analysis mentions both, we'll figure it out later.
