How would a duel between a Magic: The Gathering and Yu-Gi-Oh! deck go, and what would the rules be? How would it work?

Both at FULL POWER:

Turn 1: Magic goes first

Magic: I activate a land…..

Yugioh: I negate

Magic: Wait what? You haven’t even played any cards yet, what are you negating with?

Yugioh: A little thing called Handtraps,

Magic: Then I ….

Yugioh: Negate that as well

Magic: Screw you, pass

Yugioh: Great, I summon …..

*5 minute of shuffling cards on the field later*

Yugioh: and attack for game?

Magic: Activate instant?

Yugioh: Negate with CDI, gg

In order to avoid a situation like above Magic would need to sped way, way up and Yu-Gi-Oh way, way down.

For Magic:

• Activate 2–3 lands per turn
• All cost are halved
• Draw 2–3 cards each turn

For Yu-Gi-Oh:

• Only 3 monster and spell zones
• 800 ATK or LP = 1 Power/Toughness or LV
• Starting hand of 3 cards
• Monsters can’t attack the turn they are summoned

With this maybe they could have a game that’s not completely one sided

Then there are some straight up irreconcilable differences, such as

• In Yu-Gi-Oh you choose what monster your monster attacks,
• In Magic your opponent chooses what creature your creature attacks.

Which one to use? Eu não tenho idéia.

Mas mesmo assim os fundamentos do jogo ainda favorecem o jogador Yu-Gi-Oh....

Não só o jogador mágico teria que sobreviver aos primeiros 2-3 turnos, já que Yu-Gi-Oh é extremamente explosivo, eles precisariam sobreviver também aos 4-10 turnos, já que Yu-Gi-Oh se sobressai na recuperação de posições ruins.

Bambos os jogos são feitos para operar em velocidades irreconciliavelmente diferentes, então eu recomendo apenas jogá-los separadamente
