Best star power for Cosmo

Precession is the star power in the site's recommended Cosmo build. Star powers are passive, so this one works on its own for the whole match once it is equipped; the alternative is Ammo Attractor. Loadout pick rates were never measured for Cosmo, so this is a recommendation, not a counted majority.

Best gadget for Cosmo

Telescope Trap is the gadget in the recommended build. A gadget triggers on its own with only a cooldown between uses, so the pick is the effect worth reaching for again and again; the alternative is Planetary Pushback.

Best gears for Cosmo

The recommended pair is SHIELD and DAMAGE. Gears add a smaller stat boost than a star power or gadget, so the slot fine-tunes the build rather than defining it.

What players who own Cosmo have unlocked, counted from tracked profiles over the last 30 days. "Unlocked first" is the share among the players who own only one of a pair, which is the closest thing to a preference the game data exposes: Supercell never publishes which build a player equipped in a match, so nothing here is a pick rate or a win rate by build.
