I want to build a rain team, but I want something that's a reliable switch in to Jolteon and Thundurus-T without also being a huge gimmick that doesn't really service the team (i.e. Lanturn). Any suggestions as to what can check both (i.e. resists ice and electric for HP Ice and Thunderbolt, preferably resists fighting in case of Focus Blast too) and OHKO or capitalise on the switch (i.e. a set-up sweeper)? Maybe some sort of scarf user (who isn't OHKO'd by the pair, but can outspeed OHKO the following turn)?
To get a scope of what's currently going to be on the team, I'm going with Rain Dance Manaphy (U-Turn, Scald, Rest, Rain Dance), Life Orb Keldeo (using HP Rock to OHKO Charizard-Y, Surf to OHKO Hippowdon and Sacred Sword to OHKO Ttar) and Specs Latios (Psychic to OHKO Mega-Venusaur) - which is pretty decent and powerful coverage - but the BoltBeam weakness really hampers me. For the remaining team members I need another rain-maker, a physical heavy hitter, but most importantly something which doesn't fear ice or electric attacks.
