Ob Nixilis can make his opponent discard cards and lose life, or draw cards and take damage. He can gain life, summon [[#Red Devil|Red Devil tokens]] and give {{Ability|Haste}}, {{Ability|Berserker}} and {{Ability|First Strike}} to the tokens. Although temporary buffs are usually only categorized as such, the Berserker given to the Red Devils is categorized separately, because of the synergy with the Red Devils' death ability.
