From those choices I would have to say either Infernacatty or Flyvire DAX-Lock is a really bad deck from what I hear but the Empoleon verient may work in the end it all comes down to your metagame.
I think the most usefull deck that you said is Infercatty becuase is really fast and can do lots of damage only with few energy.
I'm going to vote in Infercatty.
Blissey is amazing. Electivire is a decent combo with it. That'd be my choice, the card just destroyed a large portion of the BRs that it showed up at.
Please enlighten me, most people from the first page of this thread, how did your amazing DAX-LOCK do, during Battle Roads?
Also, anything with Blissey in it is the bdif.
