Flip 3 coins. This attack also does 20 damage for each heads to each of your opponent’s Benched Pokémon.
Mega Slowbro ex fires Laundry-Go-Round for 90 damage to the active plus 20 damage per heads flip to each of your opponent's Benched Pokémon — up to 60 per benched Pokemon per flip with all 3 heads. The win condition is accumulating bench damage alongside active KOs to threaten multiple opponents' Pokemon simultaneously.
Open with Slowpoke searched by Poke Ball and begin attaching water energy while drawing with Professor's Research and Copycat to find Mega Slowbro ex. Mantyke provides a supporting Basic that sits on the bench. Once Mega Slowbro ex is active with 3 energy, Laundry-Go-Round hits the active for 90 and flips 3 coins — each heads deals 20 to each benched Pokemon. Heavy Helmet punishes opponents who attack back. Mid-game, Irida and Misty accelerate water energy attachment. Training Area provides additional support. The game plan compounds over several turns as bench damage from coin flips chips down the opponent's entire roster.
Laundry-Go-Round maximum output
90 dmg to active + (20 × 3 heads × 3 benched) = 90 active + 180 bench (max)
All 3 coins heads; bench of 3 — each benched Pokemon takes 60, totaling 180 bench damage plus 90 to the active. Average expected bench damage per benched Pokemon is 30 (1.5 expected heads × 20).
Each Laundry-Go-Round flip that hits applies 20 damage to every benched Pokemon. Over 3-4 turns even average flip results accumulate damage across the bench. When bench damage pushes opponents to low HP, Cyrus or Calem can drag one up for a clean KO, scoring points without requiring a Laundry-Go-Round high roll on that turn.
Irida and Misty accelerate water energy onto Mega Slowbro ex to reach the 3-energy threshold faster. Pokémon Communication can find Mega Slowbro ex if Poke Ball has already searched Slowpoke but Mega Slowbro ex has not yet appeared. Training Area supports consistent energy attachment. Inflatable Boat provides a mobility option to reposition Mega Slowbro ex if needed.
Laundry-Go-Round deals 20 damage to each benched Pokemon per heads flip. If you bench only one or two Pokemon, total possible bench damage is lower and every flip delivers less value. Playing a narrow bench reduces the impact of each coin flip significantly and forces Mega Slowbro ex to rely on the 90 active damage alone.
Mega Slowbro ex has 200 HP and a retreat cost of 3, making it nearly immovable once active. Grass-type attackers like Victreebel exploit type advantage to reach one-shot thresholds. Wugtrio ex (25% win rate against this deck) provides another vector. Scoring 3 points from one KO ends the game immediately — commit resources to that single hit.
The spread damage strategy only pays off when bench chip accumulates to KO thresholds. Pokémon Center Lady or equivalent healing removes that accumulation and forces Mega Slowbro ex to redo multiple turns of damage work. Healing a benched Pokemon from 40 damage back to full HP negates roughly two average flip turns of spread damage.
