Seizan, Perverter of Truth | Legendary Creature | Demon Spirit | At the beginning of each player's upkeep, that player loses 2 life and draws two cards. | Maji

Obosh, the Preypiercer | Legendary Creature | Hellion Horror | 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} any time you could cast 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. | Denis Medri

Jegantha, the Wellspring | Legendary Creature | Elemental Elk | Companion — No card in your starting deck has more than one of the same mana symbol in its mana cost. (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.) {T}: Add {W}{U}{B}{R}{G}. This mana can't be spent to pay generic mana costs. | Steve Ellis
