Rules

The ONLY monsters allowed in the main & extra decks are archetypal ones
If your deck has an archetypal/type/attribute field spell you can play terraforming/metaverse
The ONLY spell/traps allowed are archetypal ones and ones that support the types/attributes included within your archetype. Example:

Speedroid dupligate can be played in any wind deck, despite having speedroid in the name because it is generic wind support.
If your deck contains Dark Monsters, you can play cards like Allure Of Darkness since it directly supports Dark Monsters
You cannot play cards like Trade-In because your deck contains Level 8 Monsters

Spells/Traps that summon non-archetypal monsters of your type/attribute CANNOT be played, that means no Shade Brigandine in Warrior Decks or One Time Passcode in Cyberse decks.
Cards like Poisonous winds is not support for winds, it is anti-support and therefore not allowed. Same for cards like Light and Shadow Imprisoning Mirror.
You can play any other card names mentioned on archetypal cards, E.g. Red-eyes can play Dark magician for Red Eyes Dark Dragoon.

Note: This does not mean aromage gets every plant monster because jasmine can search it, those are not named individually on the card.

Generic Gemini/Ritual/Fusion/Synchro/Xyz/Pend&Link support is NOT allowed, this is stuff like supervise,preparation of rites,fusion recycling plant,synchro overtake,xyz import,pendulum treasure&link bound
If your deck has a Toon monster you cannot play toon support such as toon terror. The exceptions to this is Polymerization in the case your deck has a fusion monster but no archetypal fusion effect
Banned monsters are not allowed even if it's part of your archetype. That means you cannot play Master Peace, the True Dracoslaying King even if you spun True Draco from your Tier Wheel.
