Yeah, I've clearly not been keeping up with the game cause I have no idea what the hell any of that is.

Master Rule = the rules of the game. In Master Rule 4, an extra type zone was added to the game board called the "Extra Monster Zone", of which 2 are on the middle of the board. Each player can summon a single extra deck monster (Fusion, Synchro, Xyz, Pendulums that were sent there, Link) to one of those zones, after which they can no longer summon a monster from the extra deck *unless* they have a link monster pointing to one of their other monster zones, or unless the monster in their extra zone is destroyed or moved somewhere else.

Link monsters are monsters summoned from the extra deck that contain up to 8 arrows on their cards, with each arrow equalling one monster you need to sacrifice for its summon. Those arrows point diagonally, horizontally and vertically, which is how they point to certain zones to allow for summoning.

Pendulum monsters are like regular monster cards, but two of them can be played in the Spell and Trap zones as Spell cards. When two of them are there, look at the pendulum scales printed on the cards. Unless the card says otherwise, once per turn, you can summon any number of monsters from your hand with levels that are in between the Pendulum scales of your two pendulum monsters (so if you had a scale 1 and a scale 3, you can only summon level 2 monsters. if that scale 3 was a scale 7, you can summon anywhere from level 2 to level 6.)

Additionally, pendulum monsters that are destroyed on the field go to your Extra Deck instead, from which they can be pendulum summoned back, but the same rules apply to them as to Extra Deck monsters (where you cannot summon more than 1 without a link monster)

Under master rule 5, the restrictions on extra deck monsters were lifted and you could now summon as many as you like again, with two exceptions: Pendulums, and Links. For links it makes sense since they get effects based on if they're pointing to another link monster or not, but for pendulums this rule absolutely guts them as they are meant to come back into play over and over. Therefor, I would lift the restriction and allow a player to summon any number of Pendulum monsters from their extra deck again, regardless of whether or not they have a link monster pointing to a zone.

if this sounds confusing, don't worry. It is.
