No, because Swords Dance + Fire Fang delivers around 78% to the standard Bronzong. Having said that, Bronzong is capable of using Explosion and exploiting Garchomp's unability to OHKO it in the first place. However, if your Bronzong's equipped with Explosion, the chances are you already used Explosion prior to Garchomp's initial switch-in is likely. You see, Bronzong is naturally a Pokemon that leads off with the commonly used Steath Rock and Hypnosis combination. On the other hand, Garchomp's Swords Dance set is understandably a late-game sweeper, even though it is more than capable of establishing its presense felt earlier in the game.
Two Pokemon with Ice Beam, as too with one of the two being able to outspeed Garchomp is 'countering' the landshark. Cressilia can take one Outrage after a single Swords Dance, so that grants you a free Ice Beam hit. Afterwards, Cressilia will faint, and then you have to switch in your Deoxys, Starmie of any other Pokemon you posess to outspeed Garchomp and take it down cleanly. Remember, though, as there's always a chance of Sand Veil's activation, so it's not a fullproof way of dealing with Garchomp.
