Obsidian-Feuerherz

{1}{R}{R}: Lege eine Glutmarke auf ein Land deiner Wahl, auf dem keine Glutmarke liegt. Solange auf dem Land eine Glutmarke liegt, hat es „Zu Beginn deines Versorgungssegments fügt dir dieses Land 1 Schadenspunkt zu." (Das Land brennt weiter, nachdem das Obsidian-Feuerherz das Spiel verlassen hat.)

Corazón ígneo de obsidiana

{1}{R}{R}: Pon un contador de llamarada sobre la tierra objetivo sin un contador de llamarada sobre ella. Mientras una tierra tenga un contador de llamarada, tiene "Al comienzo de tu mantenimiento, esta tierra te hace 1 punto de daño". (La tierra continúa quemando después de que el Corazón ígneo de obsidiana dejó el campo de batalla.)

Cœur de feu d'obsidienne

{1}{R}{R} : Mettez un marqueur « brasier » sur le terrain ciblé sans marqueur « brasier » sur lui. Tant que ce terrain a un marqueur « brasier » sur lui, il a « Au début de votre entretien, ce terrain vous inflige 1 blessure. » (Le terrain continue de brûler après que le Cœur de feu d'obsidienne a quitté le champ de bataille.)

Cuoreinfuocato di Ossidiana

{1}{R}{R}: Metti un segnalino fiamma su una terra bersaglio che non ha un segnalino fiamma. Fintanto che quella terra ha un segnalino fiamma, ha "All'inizio del tuo mantenimento, questa terra ti infligge 1 danno". (La terra continua a bruciare dopo che il Cuoreinfuocato di Ossidiana ha lasciato il campo di battaglia.)

黒曜石の火心

{1}{R}{R}：猛火カウンターが置かれていない土地１つを対象とし、それの上に猛火カウンターを１個置く。 その土地の上に猛火カウンターが置かれているかぎり、それは「あなたのアップキープの開始時に、この土地はあなたに１点のダメージを与える。」を持つ。 （この土地は、黒曜石の火心が戦場を離れた後も燃え続ける。）

Alma Avérnea de Obsidiana

{1}{R}{R}: Coloque um marcador de labareda no terreno alvo sem um marcador de labareda. Enquanto aquele terreno tiver um marcador de labareda, ele terá "No início de sua manutenção, este terreno causa 1 ponto de dano a você." (O terreno continua a queimar após Alma Avérnea de Obsidiana deixar o campo de batalha.)

Обсидиановый Полыхатель

{1}{R}{R}: положите жетон пламени на целевую землю без жетона пламени на ней. Пока на той земле есть жетон пламени, она имеет способность «В начале вашего шага поддержки эта земля наносит вам 1 повреждение». (Земля продолжает гореть, после того как Обсидиановый Полыхатель покинул поле битвы.)

焰心黑曜妖

{1}{R}{R}：在目标不具火灾指示物的地上放置一个火灾指示物。 只要该地上有火灾指示物，它便具有「在你的维持开始时，此地对你造成1点伤害。」 （即使焰心黑曜妖已离开战场，此地依旧继续燃烧。）

Obsidian Fireheart

{1}{R}{R}: Put a blaze counter on target land without a blaze counter on it. For as long as that land has a blaze counter on it, it has "At the beginning of your upkeep, this land deals 1 damage to you." (The land continues to burn after this creature has left the battlefield.)

Archenemy: Nicol Bolas

{1}{R}{R}: Put a blaze counter on target land without a blaze counter on it. For as long as that land has a blaze counter on it, it has "At the beginning of your upkeep, this land deals 1 damage to you." (The land continues to burn after Obsidian Fireheart has left the battlefield.)

Zendikar

{1}{R}{R}: Put a blaze counter on target land without a blaze counter on it. As long as that land has a blaze counter on it, it has "At the beginning of your upkeep, this land deals 1 damage to you." (The land continues to burn after Obsidian Fireheart has left the battlefield.)

A land with a blaze counter on it is an illegal target for this ability. You may activate the ability targeting a land, then activate the ability in response to itself targeting the same land. Although the first ability to resolve will put a blaze counter on that land, the second ability to resolve won’t resolve.

As the reminder text indicates, whether the targeted land has the triggered ability that’s been granted to it depends only on whether it has a blaze counter on it, not on whether Obsidian Fireheart is still on the battlefield.

If a land ends up with more than one blaze counter on it (thanks to Doubling Season or Gilder Bairn, for example), the ability still only causes it to deal 1 damage to its controller each turn.

If all blaze counters on a land are moved to a different land, the triggered ability doesn’t follow them. The first land no longer has the ability because it no longer has a blaze counter on it. The second land doesn’t have the ability because Obsidian Fireheart didn’t target it.

The ability gained by the land triggers at the beginning of the upkeep of the land’s controller, not the beginning of the upkeep of Obsidian Fireheart’s controller. The player who controls the land at the time the ability triggers is the one who’s dealt damage.
