ROTA-JP061 燦幻封炉 Sangen Fuuro
Continuous Spell Card
You can only use the (2)nd effect of this card’s name once per turn.
(1) Once per turn, when a monster(s) is destroyed by battle involving your FIRE Dragon monster: You can target 1 of those destroyed monsters; Special Summon it to your field in Defense Position.
(2) During your opponent’s End Phase: You can pay 1000 LP, then target 1 “Sangen” Spell/Trap in your GY; Set it, but banish it when it leaves the field.

Note: The Kanji 封炉 here means literally Sealed Furnace (likely a reference in Chinese to Freezing a Nuclear Reactor by flooding it with boric acid) but is a homonym play on 副露 a term in Mahjong to declare a kong or to call a discarded tile to complete a meld.
