If something isn't working, change it up. For instance, you have Dragon/Steel, right? You can use Ferrothorn, Excadrill, Scizor, Magnezone, Skarmory, Bisharp, Aggron, Lucario, Klefki, Heatran, Metagross ...and that's only considering one of your types. Dragon is more limited, I know, but almost all Dragons are viable. Stuff like Dragonite, Lati@s, Garchomp, Salamence, Hydreigon, etc. If something doesn't work for you, try something new. For instance, after my battle with srinator (which I got wrecked in), I rechallenged him with a new team and won 4-0.
