StrategyThe overall strategy is to block the opponents attacks. Mr Cool works as a stall deck but can also deal out heavy damage. Use Porygon's texture magic to resist the opponents attacks and change your opponent's weakness to psychic. Then If if they try to hit for 40+, neutralize them with Mime.
Recycle Energy is a star in this deck. It can allow you to retreat every turn when you need to switch between Mime and Porygon, plus it works great with Super Energy Removal. Doduo/Dodrio can soak up a few hits while you build and will provide you with free retreat to switch as much as you like. Full Heal energy is great for preserving Mime's invisible wall and preventing damage from poison. Pluspower is best used with meditate as it also powers up the next meditate etc. Garbage run can get you back psychic energies if they get discarded.
MetagameThis deck absolutely destroys single-type decks like Rain Dance, and does very well against most psychic decks. Mr Mime neutralizes legendary Zapdos as well. Dodrio negates Hitmonchan and Magmar. The deck's biggest threat is probably Alakazam, so be sure to adjust your strategy when you come up against him - Itemfind your Garbage Run and your lass.
Enjoy!
