Part of this new progression system includes a mastery tree, allowing players to gradually learn more about the five colors of mana and how each type of deck plays: Players can "skip the tour" if they wish to unlock all the different play queues, but you'll still need to play in order to earn your rewards
Theme decks - Theme decks are pre-built decks that're ready to play out of the box and are based around a particular game mechanic or Pokemon type

Makes the card just as strong at full power, BUT more interactive before that can happen Combined the Shuffle and floating effects into an optional quick effect that lets you summon out your Forbidden One monsters en masse from attachment, GY and/or Banishment Gave it a new effect that, once per phase, attaches a Forbidden One material to itself from almost anywhere of its users AND, to offset the lost Match Winner part, the card now deals piercing battle damage And gains 20,000 Original ATK/DEF while it has all 5 Forbidden One cards as attached materials, AND it deals piercing battle damage even WITHOUT all 5 F.Os attached to it So while its not going to win Matches in one go, itll still win Duels with potentially enough damage to win entire matches anyway (at 25,000 ATK/DEF, a direct hit would result in enough damage to wipe out your opponents LP 3X over with some 1000 damage to spare, AKA more than enough for the individual 3 duels in a match, so it KINDA keeps in the spirit of the OPs idea.)

In the previous example, we can see that Perimeter Enforcer has a 100% chance of being in the Detectives packet
