Attract+Synthesis+Double Team

If he protects the first action, Synthesis+Double Team~Attract
If he does a combo with a super-effective move on the first action, Protect+Double Team~Attract
If he combos with an SE move in the second action but did not Protect the first action, Double Team~Protect+Attract

I'll leave this under the hands of the RNG goddess. I actually expected a lot more on Grassy Terrain xD
