On turn one, prioritise finding Mareep or Mega Ampharos ex and getting a basic on the bench so you can evolve next turn. Use Professor's Research or Poké Ball aggressively if your opener is weak. Avoid attaching Lightning energy to a Pokémon that will never attack.
By the mid game, Mareep should be online with a back-up attacker on the bench. Sequence knockouts so each attack sets up the next. Use Cyrus to drag damaged opposing Pokémon active, and Sabrina to force unfavorable switches.
Late game, count remaining prizes and build the exact line that closes the game. If ahead, deny the comeback with Sabrina; if behind, look for a single-turn knockout chain through Mareep.
Mareep appears in nearly every tournament list and defines the archetype. If you cannot craft it, consider a different deck rather than substituting.
Iono is the closest universal draw Supporter if you are short on Professor's Research, though it trades raw card quantity for a hand reset.
Sabrina forces a switch from the opponent's choice; less precise than Cyrus but keeps disruption pressure.
Pokémon Communication swaps a Pokémon in hand for any from the deck — useful if Poké Ball's random pull is unreliable for this build.
