Special Summons 1 Level 4 DARK monster from your Graveyard to your field.
Great ATK stats.
A big disadvantage as it depends on Spell cards resolution during your opponent’s Main Phase makes this card’s effect activation to be very challenging.
This monster requires 2 Tributes to Tribute summon.
Special summons a level 4 monster only, not level 4 or lower.
If your opponent activates a Spell card during their Main Phase, it also counts as the trigger condition for your Dark Horus to activate its effects.
Mausoleum of the Emperor allows you to pay 2000 Life Points in order to Normal Summon Dark Horus. Mecha Phantom Beast Hamstrat generates tokens upon flip summon, and Double Coston counts as 2 Tributes when being used for a Tribute Summon of a DARK monster.
Using Transmodify Spell card, you can send Red Eyes Black Dragon to the Graveyard, Special Summon Dark Horus from your Deck.
