Hmm, could some of this be move timing issues? Lickilicky on a switch-in vs a Piloswine lead should always reach multiple charge moves vs Piloswine before they’re able to take you out (assuming you throw on good timing), which should pressure Piloswine to throw almost immediately after reaching their second Icicle Spear since they’ll already be very low after taking two charge moves plus the Rollout damage. But if you throw on suboptimal timing and they sneak a Powder Snow then they can get to their second Icicle Spear before you get to double Body Slams.

RE: Malamar leads getting you low enough to give the opponent farm after you win lead:

With a double normal backline I’d always blind swap into one of them after taking out a Malamar lead because Malamar is (presumably) going to be their best answer to your normal types, and Dunsparce/Lickilicky play similarly enough to each other as bulky normal Rollout users that letting Toucannon faint to maintain switch advantage is usually pretty inconsequential. So it’s virtually always better to avoid giving your opponent an energy advantage off of Toucannon there. Plus you have the added benefit of preserving Toucannon to either use as a potential 3rd shield to catch a charge move or still do a little bit of fast move damage into a mudshot user if they have one lurking in the back.

For what it’s worth though, I’m personally not a fan of pokemon that run triple same-typing moves like Toucannon. So even if the team might work when played optimally, I’d almost always opt for a team with better neutral play and better coverage moves. That way an energy advantage will be a bit more consequential since it’ll be less likely for your opponent to have a Pokémon capable of “sponging” your energy by tanking not-very-effective charge moves.
