What does this set do?
Scarf Infernape gives us the revenger we need that can reliably deal with almost every Pokemon on the other team. It outright beats Cube, being faster and stronger enough to OHKO, which is huge right now. Flare Blitz hits Jirachi for SE damage, while being Infernape's strongest STAB move with the EV spread. CC hits Cube, HP Ice hits Landorus, and U-Turn destroys Azelf while letting us get away from Slowbro. U-turn also alows for a strong VoltTurn core that has been started in the team already.
How can this set help the team?
This set fills the only need to the team right now which is a Scarfer. It also beats Kyurem-B, which is a huge need right now as it reinforces Garchomp to do its job and destroy most of the other team. U-Turn also gives the team huge momentum against the opponent, completing the VoltTurn core that was started but never finished. (Read ganj's post about ScarfRachi earlier, Infernape pretty much can do all that except the 2HKO part depending on the move)
What can the other team do in response to this set?
Jellicent is there, but hey, U-turn. Even though U-Turn isn't 100% reliable. Team 1 can always pick a user of Aqua Jet, as that will outright stop Infernape. Scarf MoxieMence was brought up, but I think HP Ice should be enough after SR. Gyarados is also a threat, but is stopped between Rotom-W and Zapdos (which we can U-Turn to!). The biggest threats right now are Lati@s and pretty much water types, but Water Types should be manageable. If anyone has tips for Lati@s, please don't hesitate to ask.
I don't think I need calcs, but will post them if needed.
