Defeating Cliff Shadow Omanyte Team, in Pokemon go

Today I'm facing Cliff, a Team Go Rocket Leader and I bring to this fight a Sceptile, Machamp and Venusaur. I choosed 2 grass types because according to the pokemons that cliff can use, his team is very weak against this typing. I beated Cliff only using Sceptile with Bullet Seed/Leaf Blade, a deadly and fast combination of attacks against Cliff current team. Portugal, Algarve, Albufeira.
