As the title suggest, this deck main attacker is Radiant Greninja, although there is no Ash's Greninja in the current standard format. Moonlight Shuriken is devastating, destroying engine like there is no tomorrow. Backup attacker Zoroark with phantom transformation which can turn into Flappe, Appletun, Mightyena, or Slowbro when needed. There is Also Starmie V for some scenario.
