Thoughts?
My ace spec i'm debating about currently, between Computer search or Dowsing machine
I want to add a 4th candy (somehow my 4th went missing << Not sure what to take out tho.
I dont have the money for beachs atm so there no real way I can obtain them, and I'm affraid to buy them now before we see if they'll be reprinted cause I'd hate to have a expensive card that I could'nt use for next season play (not going to nationals so)

So other then trop. what would you add or take out of this deck, I kinda wanna play around with the idea of 3 BK Ex's but then again I run super rod so worst comes to worst I can super rod them back. Just trying to get ready for upcoming battleroads.

Also want to add a scarper but what would I take out?

You should take out both Colress. You need to get set up, and Colress is prohibiting that. I would say:
-2 Colress
+1 Tool Scrapper
+1 N (One of the best if not the best draw supporter in format)

Maybe I feel colress is a viable card now with Plasma Box being the deck that I'll probs see most of, It might suck first turn but more then likely first turn im junipering or skylaing for something, plus Id be dropping a draw card for a non draw card which I feel would slow down my deck. I feel N is good but the goal of my deck is to OHKO with BK EX fast so more times then not im prize advantage, you have to think once I KO any EX N turns into a 4 card draw were colress at that time passes N out in draw power.
