Deathmatch
A Deathmatch is a type of Pokémon battle introduced in Pokémon Sardonyx: Raised to Win. A Deathmatch involves two Trainers battling each other, both using a single Pokémon. It is the primary form of battling within Altaris' Circuit. As a result, the only people that are known to challenge the player to Deathmatches are Circuit Trainers and members of Team Mortis. As the name suggests, a Deathmatch is a battle to the death. It is for this very reason that Deathmatches are illegal.
Mechanics
In most deathmatches, the player is only allowed to use one Pokémon to battle their opponent with. The Pokémon used for the battle is chosen by the player prior to the start of the battle.
The player is not allowed to use items from their bag during deathmatches. They are only allowed the item their Pokémon is holding.
If the player's Pokémon faints in a deathmatch, they are marked as dead.
