I thought of a Rock, Paper, Scissors competitive minigame that's in the coliseum tab.

It's called Monster Brawl.

How does it work?

There are actually six choices instead of three.

Fiend, Undead, Slime, Beast, Construct, and Gremlin

What it basically is that on one side, a knight will possess monsters, while another knight has possession over monster on the other side.

You choose a fiend, undead, slime, beast, construct, or gremlin creature, and the knight you're challenging chooses one and... it's rock, paper, scissors

Fiend > Gremlin, Fiend = Slime, Undead, and Construct, Fiend < Beasts
Undead > Slime, Undead = Gremlin, Beast, and Fiend, Undead < Construct
Slime > Beast, Slime = Fiend, Slime < Construct, Gremlin, and Undead
Beast > Gremlins and Fiends, Beast = Construct, and Undead, Beast < Slime
Gremlin > Slimes and Constructs, Gremlin = Undead, Gremlin < Beast and Fiend
Constructs > Undead and Slimes, Constructs = Beasts and Fiend, Constructs < Gremlins

Correct me if I made any mistakes.

Any creature that goes against its same type will be equal. Example: Construct vs. Construct

If any creature that is super effective (Don't say anything about Pokemon.) against another, but that creature is also super effective to them, then they're equal. Example: Fiends vs. Slimes, Slimes harm fiends because of their piercing, but fiends hurt them because of their shadow attacks.

If any creature that is neutral to its opponent, while its opponent is weak against them dominates their opponent. Example: A beast would be powerful against a gremlin, because a gremlin is elemental, while a best is piercing, and even though gremlins are neutral to piercing; they'd still lose, because beasts are strong against elemental.

If the creatures are both neutral towards each other, then it's equal. Example: Gremlin vs. Slime, gremlins are neutral to piercing, and slimes are neutral to elemental.

If they're both weak towards each other, then it's equal. Example: Fiend vs. Undead, they both do shadow damage, and are both strong against shadow.

There are two modes of this, but both will be one-versus-one

Simple mode: You click a monster family, and any monster from that family randomly appear.

Complex mode: You actually pick a name of a monster from the family. This would be confusing for some players that don't know all the monsters in each family, and you'd ahve to think fast.

The end.

Any suggestions, questions, and comments?
