It depends what you class as "good" but Solosis, Duosion, Reuniclus, Spritzee, Aromatisse, Sylveon and Carbink learn Skill Swap by levelling up and Abra, Drowsee and Ralts can learn it via breeding in Pokémon X and Y.
Note: Abra and Drowsee can only learn by breeding in Pokémon X and Y if the one of the parents is an Abra, Kadabra, Alakazam, Drowzee, Hypno, Mr. Mime or Spinda that has learnt Skill Swap in Gen IV via TM or in Gen V via Move Tutor.
Here is a list of Pokémon that can learn Skill Swap in another Generation that could potentially be transferred over to Pokémon X and Y using Pokémon Bank.
Hope I helped :)
