>>12074939Not really walled by "half of OU". Perfect coverage.
If you're talking about special walls, the only relevant ones are Blissey/Chansey, as even Ferrothorn isn't safe from TBolt spam since he doesn't really have reliable recovery outside of leech seed, which misses even when you don't have any boosts. You can easily replace HP ice with toxic for the blobs, too.
And of course, that's just one double team user, while you can have up to 6 on your team to cover every possible matchup.
