Following several players' "unique" list building at the start of 8th edition, spamming powerful units was heavily restricted by the implementation of this rule.
What is the Rule of Three?
Introduced in 6th Edition, this unit type was given a large number of rules that necessitated counters in listbuilding every time it has been meta.

Recently, a Chaos player went undefeated at an event using a notable list, in that a certain model that he played the entire event with was not in it.
What is a Helbrute?
Organizer of the Alamo GT and San Antonio Shootout, this person banned a player for one year for misplaying a flyer throughout of one of his events.
Who is David Villareal?
Though this army archetype is recently maligned by both Games Workshop and the competitive community, its usage of high numbers of cheap models to control the board have taken players to very high placings at many events.
What are Horde Armies?
This army, despite being relatively new at the time, was made impossible to use due to restrictions on army composition after it was used to table a highly skilled player in one turn.
What was Ork/Freeboota Buggies?
Used by the entire army of a certain faction, the 5th edition version of this rule was so strong that it became a psychic power in both 6th and 7th edition.
What is Force?
Using the rules of a subfaction of Aeldari, this army was known for being impossible to interact with, but also known for being unable to win a tournament.

One of the most infamous cheaters in the 40k scene, Frontline Gaming has received backlash about their participation in their events multiple times, usually leading to this person dropping from the event.
Who is William Abiliez?
Most popular with armies that could use high number of psykers and/or allies, this archetype would use a single unit to take on most of their opponent's army.
What was a Death Star?
The reaction to this play came in the next game with this exchange:
"We both knew what I was going to do."
"I'm not gonna let you do this."
What is Tony Grippando not letting Alex Fennel have a movement phase?
Prior to 8th Edition, this subset of units was unavailable for use in your army unless the event allowed you to do so.
What was Forge World?
This list was so strong that an entire team decided to get it nerfed by taking the exact same list to LVO, and it worked.
What was 8th Edition Iron Hands?
Despite being a great player, this person has developed a reputation for misinterpreting rules in their favor, such as forcing a Knights player to not leave their deployment zone due to misunderstood terrain rules.

What was Imperium Soup?

What was the Kroot Conga Line?

What was the LGT 2021 Finals?
The backbone of Ork viability in 8th edition alongside 6 point Boyz, this rule allowed the army to ignore the vast casualties that it accrued through absorbing enemy fire.
What was Mob Rule?
Otherwise a niche army, this old faction that was introduced in an Imperial Armor won the 2017 Las Vegas Open alongside some allies.
