You can take advantage of his low Speed by slotting Goodra in a TR Team.
A Physical Goodra is quite good only having 10 Base Stat difference compared to his SpA Stats.
A Moveset you might want to consider :
Goodra @ Leftovers/Sitrus Berry/Lum Berry
Ability: Sap Sipper
EVs: 252 HP / 252 Def/4 Atk
-Sleep Talk / Poison Tail
- Dragon Tail
This set can make Goodra an annoying wall to take down, Sap Sipper Prevents Leech Seed and Lefties can provide solid recovery. Lum Berry is good option if you aren't going for a Rest-Talk Set.
When using a TR Team remember that you have 4 turns in which to quickly deliver heavy damage and that a Set-Up can be folied quite easily
