Obosh der Beutestecher

Gefährte — Dein Startdeck enthält nur Länderkarten und Karten mit ungeraden Manabeträgen. (Falls du diese Karte als deinen Gefährten erwählt hast, kannst du {3} bezahlen, um sie von außerhalb der Partie auf deine Hand zu nehmen. Spiele Gefährte wie eine Hexerei.)
Falls eine Quelle mit ungeradem Manabetrag, die du kontrollierst, einer bleibenden Karte oder einem Spieler Schaden zufügen würde, fügt sie der bleibenden Karte oder dem Spieler stattdessen doppelt so viele Schadenspunkte zu.

Obosh, Perforapresas

Compañero — Tu mazo inicial contiene solo cartas con valores de maná impares y cartas de tierra. (Si esta carta es el compañero que eliges, puedes pagar {3} para ponerla en tu mano desde fuera del juego como un conjuro.)
Si una fuente que controlas con un valor de maná impar fuera a hacer daño a un permanente o jugador, en vez de eso, hace el doble de ese daño a ese permanente o jugador.

Obosh, le Perce-proie

Compagnon — Votre deck de départ ne contient que des cartes avec des valeurs de mana impaires et des cartes de terrain. (Si cette carte est le compagnon de votre choix, vous pouvez la mettre dans votre main depuis l'extérieur de la partie pour {3} lorsque vous pourriez lancer un rituel.)
Si une source avec une valeur de mana impaire que vous contrôlez devait infliger des blessures à un permanent ou à un joueur, elle inflige le double de ces blessures à ce permanent ou ce joueur à la place.

Obosh, il Trafiggiprede

Compagno — Il tuo mazzo iniziale contiene solo carte con valori di mana dispari e carte terra. (Se questa carta è il compagno che hai scelto, puoi aggiungerla alla tua mano dal di fuori della partita come una stregoneria, pagando {3}.)
Se una fonte che controlli con valore di mana dispari sta per infliggere danno a un permanente o a un giocatore, infligge invece il doppio di quel danno a quel permanente o a quel giocatore.

獲物貫き、オボシュ

相棒 ― あなたの開始時のデッキに、マナ総量が奇数のカードと土地・カードのみが入っていること。（このカードがあなたの選んだ相棒であるなら、あなたはソーサリーとして{3}を支払うことでゲームの外部にあるこれをあなたの手札に加えてもよい。）
あなたがコントロールしていてマナ総量が奇数である発生源１つがパーマネントやプレイヤーのうち１つにダメージを与えるなら、代わりにそれはそのパーマネントかプレイヤーにその点数の２倍の点数のダメージを与える。

Obosh, o Furapresa

Companheiro — Seu deck inicial contém apenas cards com valores de mana ímpares e cards de terreno. (Se este card for seu companheiro escolhido, você pode colocá-lo em sua mão de fora do jogo por {3} como um feitiço.)
Se uma fonte que você controla com valor de mana ímpar for causar dano a uma permanente ou a um jogador, em vez disso, ela causará o dobro daquele dano àquela permanente ou àquele jogador.

戕害狱兽奥巴什

行侣～你起始套牌中仅包含地牌和法术力值为奇数的牌。（如果你选择这张牌作为你的行侣，则你可以在法术时机下支付{3}来将它从游戏外置于你手上。）
如果某个由你操控且法术力值为奇数的来源将对任一永久物或牌手造成伤害，则改为它对该永久物或牌手造成两倍的伤害。

Obosh, the Preypiercer

Companion — Your starting deck contains only cards with odd mana values and land cards. (If this card is your chosen companion, you may put it into your hand from outside the game for {3} as a sorcery.)
If a source you control with an odd mana value would deal damage to a permanent or player, it deals double that damage to that permanent or player instead.

If a card in a player's library has {X} in its mana cost, X is considered to be 0.

For spells with {X} in their mana costs, use the value chosen for X to determine the spell's mana value. If a permanent or card in any other zone has {X} in its mana cost, X is considered to be 0.

Before shuffling your deck to become your library, you may reveal one card from outside the game to be your companion if your starting deck meets the requirements of the companion ability. You can't reveal more than one. It remains revealed outside the game as the game begins.

If a creature with trample you control would deal combat damage to a blocking creature while you control Obosh, you must assign its unmodified damage. For example, a 3/3 creature with trample blocked by a 2/2 creature can have 1 damage assigned to the defending player. It will then deal 4 damage to the blocking creature and 2 damage to the defending player.

If an effect such as that of Ravenous Gigantotherium asks you to divide damage among targets, you must divide the unmodified damage before doubling it.

If more than one player wishes to reveal a companion, the starting player does so first, and players proceed in turn order. Once a player has chosen not to reveal a companion, that player can't change their mind.

If multiple replacement or prevention effects try to modify damage that would be dealt to a permanent or player, the player or the controller of the permanent chooses the order in which they apply.

If you reveal a companion outside the game, for as long as it remains there, you may pay {3} any time you could cast a sorcery (that is, you have priority during your main phase and the stack is empty). Once you do, you put it into your hand and behaves like any other card you've brought into the game. For example, if it's discard, countered, or destroyed, it's put into your graveyard, remaining in the game. This is a change from previous rules.

Paying {3} to put your companion into your hand is a special action. It doesn't use the stack and players can't respond to it. Once you take this action, you may cast that card if it's legal to do so before any other player can take actions.

The companion ability has no effect if the card is in your starting deck and creates no restriction on putting a card with a companion ability into your starting deck. For example, Zirda may be in your starting deck even if your other permanent cards don't all have activated abilities.

The companion's other abilities apply only if the creature is on the battlefield. They have no effect while the companion is outside the game.

The requirements of the companion ability apply only to your starting deck. They do not apply to your sideboard.

You may have one companion in the Commander variant. Your deck, including your commander, must meet its companion requirement. Your companion is not one of your one hundred cards.

Your companion begins the game outside the game. In tournament play, this means your sideboard. In casual play, it's simply a card you own that's not in your starting deck.

If you reveal a companion outside the game, for as long as it remains there, you may pay {3} any time you could cast a sorcery (that is, you have priority during your main phase and the stack is empty). Once you do, you put it into your hand and behaves like any other card you've brought into the game. For example, if it's discarded, countered, or destroyed, it's put into your graveyard, remaining in the game. This is a change from previous rules.

Once you put your companion into your hand, it behaves like any other card you’ve brought into the game. For example, if it’s countered or destroyed, it’s put into your graveyard, remaining in the game.

Wizards of the Coast has issued functional errata for the Companion mechanic. Instead of casting companions from outside the game: Once per game, any time you could cast a sorcery (during your main phase when the stack is empty), you can pay {3} to put your companion from your sideboard into your hand. This is a special action, not an activated ability. It happens immediately and can’t be responded to. It can’t be countered or stopped by cards like Phyrexian Revoker.

The damage is dealt by the same source as the original source of damage. The doubled damage isn't dealt by Obosh unless it was the original source of damage.
