Obosh, the Preypiercer

Card text

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.

Official rulings

The 8 most recent official rulings for Obosh, the Preypiercer, newest first.

• 2023-04-14 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.
• 2020-06-01 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.

• 2020-06-01 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.
• 2020-06-01 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.

• 2020-04-17 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.
• 2020-04-17 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.
• 2020-04-17 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.
