Arraia do Brilho Abissal

As Deepglow Skate's ability resolves, you must double each kind of counter on the permanents it targets.

To double the number of each kind of counter on a permanent, put another counter on it for each counter it already has. Effects that interact with counters being put onto permanents apply as appropriate.

You can choose no targets if you don't want to double the counters on any permanents.
