You could use Tapu Lele SM7b and attach a Fairy Charm to achieve automatic confusion from the bench.
Thanks. I knew there was a consistent way to spread confusion, and io and behold, Tapu Lele synergizes incredibly with Slurpuff. If you include ULP Magearna you can also attach the relevant fairy charm to Slurpuff, providing a 2-way disruption. I heavily dislike Breloom because of the reliance on the sleep mechanic, and therefore Slumber Forest, and therefore easily losing to something like Escape Board - Fairy is going to be a really relevant weakness come Cosmic Eclipse, with the BDIF probably being ReshiZekrom, people teching Naganadels and Naganadel/Guzzlord, and decks using the creation trio too. The deck having a control angle with the fairy charms, and also having the option to stall it out with A-Ninetales and Wondrous Labyrinth makes it a more appealing anti-meta archetype to build for me, unlike Breloom that relies on hax and having its game plan go uninterrupted.
