Is the ParaFlinch Togekiss set banned in OU?

Question

Togekiss is a ParaFlinch set, with Thunder Wave and Air Slash with the Ability Serene Grace.
However, according to Smogon OU rules:
• Endless Battle Clause: Any moveset on any Pokémon that is capable of intentionally causing an endless battle is banned from competitive play.
So is the ParaFlinch set considered an endless battle?

Answer 1

No. What you are telling about an endless battle doesn't count.

Some of you may be aware of a strategy going around that can force battles to continue indefinitely. This involves using Leppa Berry with Heal Pulse, Recycle, a healing move (such as Slack Off or Soft-Boiled) and Block/Mean Look/Spider Web. Fortunately only Slowpoke, Slowbro, Slowking, Blissey and Smeargle are legally able to use this combination (Ralts, Kirlia, Gardevoir and Gallade as well if you count Wish). To use the strategy, one of these will switch into a defensive Pokemon, or one unable to 2hko them, use Block and then PP stall the opponent with recovery and Leppa Berry + Recycle. Once the opponent begins to Struggle, the user can simply continue to Heal Pulse, with Leppa Berry + Recycle, until the opponent forfeits. An example can be seen here.
We've agreed that this strategy is not within the spirit of the game and have therefore decided to implement the "Endless Battle Clause".

It doesn't count since you are using PP. If it involved Leppa Berry + Harvest or Leppa Berry + Recycle, then it would be banned. Also, Togekiss is banned for Gen 8 1v1 , not OU.
