Dragon and Ground are common as fuck phys attacking types. If you didn't have a solution to these things you kind of deserved to lose anyway.
I'll give you another protip. If I were going to run a Garchomp, I would pack one or two Pokemon to take out his checks and counters. For example, a ttar with fire blast and ice beam to shit on Gliscor and Skarm. If I can get rid of your ability to stop chomp raping your whole team, then chomp will proceed to rape your whole team. So plan against that.
