While "Patrician of Darkness" has a powerful effect, it doesn't directly make you attack another monster on your own field. Its effect is:
"Once per turn, you can target 1 monster your opponent controls; until the end of this turn, that monster cannot attack."
Here's how it works:
1. You activate the effect: You can use "Patrician of Darkness" to target a specific monster on your opponent's side of the field.
2. The opponent's monster is disabled: The targeted monster cannot attack for the rest of the turn.
Important Notes:
* It only affects the opponent's monsters: You cannot use "Patrician of Darkness" to target and disable your own monsters.
* It does not force an attack: It only prevents the target monster from attacking. You don't get to choose or force the target monster to attack any other monster.
