This card is treated as a Normal Monster while face-up on the field or in the Graveyard. While this card is face-up on the field, you can Normal Summon it to have it be treated as an Effect Monster with this effect:● Once per turn, you can Special Summon 1 Fiend-Type monster from your hand or from either player's Graveyard. When this card is removed from the field, destroy all Fiend-Type monsters Special Summoned by this effect.
Easily special summons Fiend-type monsters from your hand or either graveyard, regardless of level.
Decent attack and defense.
Is not a fiend-type himself, so might miss out on support in fiend decks.
Needs to be re-summoned to use effect.
Monsters he special summons are destroyed when he leaves the field.
Special summon High-leveled Fiends
Special summon High-leveled Fiend-type monsters with protection effects to use as beatsticks. Archfiend Empress synergizes well with Doom Shaman, if Doom Shaman is removed from the field Archfiend Empress will be destroyed triggering her effect allowing you to special summon another high-leveled fiend except Archfiend Empress.
As a Gemini monster Doom Shaman has a lot of support options. Blazewing Butterfly revives Doom Shaman with his effect already active. While Supervise is the other way around, it makes Doom Shaman's effect active, then when he is destroyed along with Supervise you can revive him again.
