Keruga, the Macrosage (Promo Pack) [Ikoria: Lair of Behemoths Promos]

Companion — Your starting deck contains only cards with mana value 3 or greater 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.)
When Keruga, the Macrosage enters the battlefield, draw a card for each other permanent you control with mana value 3 or greater.
