RE: 4 corners(Cinccino,Donphan,Yanmega Prime, Zoroak)
I <3 this deck...I run pretty much Yanmega/Cinccino/Donphan with the Zoroark as just a tech, but it's pretty much preference as to how you want to run it. Otherwise this is just too bulky. The only thing you for sure want to bulk is Donphan, because it owns nowadays against the meta, but Cinccino? Cinccino is just to KO Yanmega with PlusPower and a full bench, you really don't need 3-3.
-1-1 Cinccino
+1-1 Donphan
Flower Shop Lady in a deck with at least 9 lines of main attackers? You really don't want that. Another Manaphy should help you with hand refreshing, however. I'd run at least 2 hand refresh Pokemon, but not Manaphy. This is a deck with very low energy costs.
-1 FSL
-1 Manaphy
+2 Cleffa
I think Judge is so much better than Copycat, since you can abuse it in so many ways, but Copycat is really just so you can draw more cards...
-1 Copycat
+1 Judge
I'd run Juniper over PONT. You already have 6 cards that can shuffle your hand into your deck, so Juniper gives things another option. Use the other slot to add another Collector, because starting with it in this deck is amazing.
-2 PONT
+1 Juniper
+1 Collector
I'd take out Exchanger for sure. You're only running 3 different types of energy, and darkness energy for Zoroark really isn't worth it, because it only has 100 HP, and might be weakened by Earthquake. So now you have 2 different types of energy, making Exchanger almost useless. Now I would add a Junk Arm and a Ruins of Alph. I like to run 4 Junk Arm, but you need at least 3 for sure, there's just so much you can abuse. And Ruins of Alph? Well, Yanmega won't affect your Donphan much anymore, so it's nice to at least run one.
-1 Exchanger
-1 Sp. Dark
+1 Junk Arm
+1 Ruins of Alph
Last but not least, I'd take out Energy Search, because you don't need energy that often. I'd also take out Dual Ball, because now you're running 4 Collector, and I'd also take out a Switch, as long as you're running 3 Junk Arm, you only need 1. Now I'd add 3 Pokemon Reversal or Pokemon Catcher, depending on if you're going to Worlds. They are just amazing cards right now, to stall or to KO Pokemon on the bench, and they almost counter some decks.
-1 Energy Search
-1 Dual Ball
-1 Switch
+3 Pokemon Reversal/Catcher
Good luck with this deck. People really overlook the potential of Cinccino as a response to Yanmega, and go ahead and run Zoroark/Donphan/Yanmega. But this build is fine too.
