These things are fucking broken. It is utterly ridiculous. Not since RBY has any sweeper dominated like Garchomp. I ask Lords for some counters, he suggests the dull options Skarmory, Bronzong and Cresselia. These counters suck.. Bronzong loses to SD Chomp. SD on the switch, then fire fang 2hkos. Bronzongs HP ice only 2hkos Chomp. Mekkah suggests that after you figure out it has fire fang, you would be entirely safe switching to Starmie. So ok, a combination of HP ice Bronzong and Ice Beam Starmie is one legitimate counter for Garchomp. Provided your opponent doesnt use Magneton, or for that matter Weavile.. Also these calculations are done with Max def bronzong. Which will also be 2hkoed by unboosted Fireblast from Life Orb Chomp.. Furthermore, you cant really use Bronzong to set up stealth rock in this situation, because if you take damage while doing so, your counter to Garchomp wont work.. Everything is basically exactly the same with Skarmory and Starmie, except that Skarm cant 2hko Chomp, which opens up the opportunity for Chomp to Dragon Claw on the switch. Then there is Cresselia. Which is utterly unuseable. It cant do shit - which is a very bad thing in DP (similar to HP ice Bronzong). But on top of that, it is so easily pursuited it is comical. It also doesnt actually counter SD chomp either, as it cant ohko and is 2hkoed. Then there is Sub Chomp to consider. The problem with all of these options is they all need to be specialised counters that are kept protected for the sole purpose of countering Garchomp because otherwise they will not work. Latias is easier to counter than Garchomp. Latias you can just switch in Tyranitar, and if it surfs, you may be 3hkoed (you can ev it easily to get around this), but otherwise you can pursuit for 2hko ( if it doesnt switch) without fear. Either that or it has specs and you can switch to an appropriate counter. Specs Surf has about a 50/50 shot at 2hkoing (much worse than Garchomp with LO FB on Skarm). Which brings me to my next point. Tyranitar is fucking broken also. It can switch into a Latias Surf and win for christs sake. I use it as my main water counter on one of my teams. It has the strongest Pursuit in the game, and it has 384 minimum special defense and 404 HP. Then on top of that, it has SS, which by itself could have made Magcargo useable.. Really, the more I battle the more I beleive it, DP would be much better off without these two. Have a nice day.
