The deck is played in 3 parts:
Part 1: discard your tools cards. To discard your tool cards from your hand you can go about it in several ways, the best is with Garbodor, with its Chuck attack you deal 50 damage for each tools cards that you discard, you can also use the Proffesor's Research or the Rottom Vstar star power.
Part 2: move your tools cards from your discard pile to the lost zone. For this you can use the attacks of your Rottom's which allows, once the tools cards are stacked in your discard pile, to one shot almost all the pokemons and thus place your tools cards in the lost zone.
Part 3: finish the job with Porygon2. At the end of the game, once all your tools cards have been moved to the lost zone, you can use Porygon2's Garbage Attack which will allow you to deal up to 360 damage.
