pre order pokemon booster box 7/16) Pitch Black Bundle including Pokémon like Mega Clefable ex Pokemon Japanese TCG: Storm Emeralda

During your Main Phase: You can send this card on the field to the GY along with 1 or more non-Tuner "Blackwing" monsters from your Deck, so that the total Levels sent equal exactly 8, and if you do, Special Summon 1 "Black-Winged Dragon" from your Extra Deck, also you cannot Special Summon from the Extra Deck for the rest of this turn, except DARK monsters

Gaining Flying is great on both offense and defense, letting you get in damage, or surprise block an opposing Flier out of nowhere on the back foot

Immerse yourself in the fascinating world with the exclusive Northblue card set and experience an adventure full of strategic duels and exciting collective companionship

Commander and Oathbreaker can both work in the same ecosystem and are not mutually exclusive

Other than that, the deck choices I think are self explanatory

I mean, 3000 attack is never something to look down on
