Altergeist Emulatelf

Continuous Trap

Special Summon this card as an Effect Monster (Spellcaster/LIGHT/Level 4/ATK 1400/DEF 1800). (This card is also still a Trap.) If Summoned this way, while it is in the Monster Zone, other "Altergeist" Traps you control cannot be destroyed by card effects, also neither player can target them with card effects.
