During Your Main Phase (Lv. 1-2-3): Once during your turn, you can Summon one Tribute Summon Spirit from your hand directly to the Field without paying its Tribute Cost. Any "When Summoned" effects the new Spirit may have do not activate when using this ability. During Your Attack Phase (Lv. 2-3): When a "Dragon Emperor" Attribute Spirit of yours attacks, send one Core from all opposing non-Tribute-Summon Spirits to your opponent's Reserve.
