I build my decks to compete against each other, so I have built a pattern that I follow on most of them to make them somewhat equal in power lvl
send 1 "Blackwing" Synchro Monster or 1 "Black-Winged Dragon" from your Extra Deck to the GY, and if you do, until the end of this turn, the targeted monster loses 700 ATK, also negate its effects
Weakness: Psychic (x2) Resistance: none Retreat: 2 Hariyama - Fighting - HP150 Stage 1 - Evolves from Makuhita Ability: Sumo Catcher Once during your turn, when you play this card from your hand to evolve one of your Pokmon, you may switch one of your opponent's Benched Pokmon with their Active Pokmon
However, a deck based around Darmanitan NXD wont be very successful as the probabilities arent in its favor for dealing enough damage consistently enough to keep up with the other Pokmon in this format
