Obosh, the Preypiercer (IKO) (Foil)

Companion — Your starting deck contains only cards with odd converted mana costs and land cards. (If this card is your chosen companion, you may put it into your hand from outside the game for {3} any time you could cast a sorcery.)

If a source you control with an odd converted mana cost would deal damage to a permanent or player, it deals double that damage to that permanent or player instead.
