From Bulbapedia, the community-driven Pokémon encyclopedia.
Vileplume's Free Agent Deck is a deck found in the Team Rocket Strategy Guide. The deck is classified as one of the advanced decks in the book, containing more rare cards than the easy-to-build decks.
Some players put a lot of faith in their Trainer cards. Dark Vileplume is a good way to gain advantage against almost any other deck. Some decks are very weak without their Trainer cards. Of course, this deck has a few Trainer cards itself. The difference is, these Trainer cards are only used to make sure you can Dark Vileplume as quickly as possible.
Once you've gotten Dark Vileplume into play, leave it on your Bench. Instead of Trainer cards, this deck has extra Pokémon. If you need to draw more cards, use Kangaskhan's Fetch attack. Instead of the Trainer card Potion, this deck has Potion Energy cards. If your Active Pokémon takes a lot of damage, you should have plenty of Energy to retreat it. Use Nidoran ♀'s Call for Family to make sure you have enough Pokémon on your Bench.
