I don't like Absol in 6C, just not that great without Mew Prime...
Kyurem or Kyurem EX would be a good replacement for Absol.
You should drop a Cheren for another Collector.
I would also drop the 2 N for 2 more PONT, N can help your opponent in the wrong scenario.
I would also drop an Eviolite for another DCE, Lost remover is big in our current format with Durant and disruption decks everywhere.
You should also post your list a new topic under DECK GARAGE if you want more input as it will get seen more...
I hope this helps, 6C is the most difficult deck to run in our current format, IMO.
