yugioh duel deck builder Yugipedia for you need to build new cards and deck Deck Builder | Master Duel

I doubt I'll ever put it together, but it could be helpful to compare notes with

Main Deck 40 The Agent of Mystery - Earth X LIGHT Level 2 [ Fairy / TunerEffect ] ATK 1000 DEF 800 When this card is Normal Summoned: You can add 1 "The Agent" monster from your Deck to your hand, except "The Agent of Mystery - Earth" or, if "The Sanctuary in the Sky" is on the field, you can add 1 "Master Hyperion" from your Deck to your hand instead

Bident of Thassa One of the best blue artifacts you can find, Bident of Thassa turns all your creatures into cats, ready to die of Curiosity

every single booster will contain 100% foil cards, and a guaranteed unique Pikachu (one of the 30 mentioned earlier) can be found in each pack

Sorcery speed effects will be judged lower

So Im only going to be talking about the one thats relevant to coin flipping
