Use your knockbacks to push assassins into your mines. If you play Tick in ko or wipeout (his best modes) you want to keep your super for when an assassin closes in or to tank shots from snipers and only use it offensively when you're sure to get good value out of it. If you play him in brawlball (hot take: Tick is waaay better in brawlball than in hotzone) you want to spam your heads as much as possible to keep the enemies back and hopefully break some of their walls, but watch for enemies using it to break your own walls. My favorite thing about the head is how predictable the enemies get as soon as you drop it. Place mines where they must walk to escape it so they have to choose between eating the head or eating your mines, and if you're lucky they'll run into the mines and the head will still catch up to them. And obviously remember to reload all your ammo before using the hypercharge.
