I don't mean to be condescending in any way but lol if your relying on excadrill or aegis to check garchomp, then your up for a bad time.Many pokes can take those 3 moves. Lots of people run air balloon steels like excadrill and aegislash. Also at +2 many pokes can be considered unstoppable and the ones that make the headlines are the ones that are hard to revenge kill and can sweep in a instant. Considering garchomp is weak to ice, fairy, and dragon which are all common types and it doesn't get a priority move can make it pretty easy to counter when we get down to it. Also the first thing someone would probably switch to when a garchomp is sent in is a counter like sk.arm
Garchomp is let me stress this, is often a wallbreaker when using life orb, tank when using the rocky helmet set, wall when using the specially defensive set to beat char y/aegis, and a sweeper when using bulky swords dance. The fact that it is a wallbreaker, tank, wall and sweeper all separated in different sets, of course. Garchomp can't be 100% countered due to it's wallbreaking sets. I can literally do an analysis breakdown for the counters but I don't think anybody in this thread wants to read an essay. There is no faster (somewhat)viable fairy type faster than Chomp other than Scarf Gardevoir. and it only beats offensive sd/wallbreaker-
252 SpA Gardevoir Moonblast vs. 196 HP / 0 SpD Garchomp: 348-410 (85.7 - 100.9%) -- 6.3% chance to OHKO
252 SpA Gardevoir Moonblast vs. 4 HP / 0 SpD Garchomp: 348-410 (97.2 - 114.5%) -- 81.3% chance to OHKO
Garchomp is in no way easy to revenge kill due to things such as: naturak bulk, bulky sd EV investment, resist berry, etc.
So instead of putting my words in an odd way in which you could easily miss them (which sorry for doing that before, as you have seemed to have missed some of my points before) let me just put a closing statement here and say: Garchomp has less true counters than Zard X, Lando-I, Thundurus-I (really thundy is only here cause of support through twave, all in all it's extremely easy to counter in my experience) Aegislash. And provides immense utility to the team by being a win condition, wallbreaker, wall, tank or scarfer. Garchomp is overall about the best scarfer in OU right now and it is impossible to outclass, and if you do, your already in S rank and cannot fulfill it's other roles. IDK why people are so opposed to Garchomp, it is a top tier pokemon with high versatility, little counters and a way to blast through all of them and has no other pokemon that outclass it. Plus it has an amazing hipster speed tier :]
