Kobyakov, Podpasok A4

Whenever a Dolbaeb creature deals combat
damage to a player, put a +1/+1 counter on it.
As long as you have a song with 5 or more likes, Kobyakov has "Whenever it deals combat
damage to a player, search your library for a "A4, Glavniy Dolbaeb" card, reveal it and put into
your hand. Exile Kobyakov."
Rather than paying Kobyakov's mana cost, you
can pay {2}{b} and exile a Dolbaeb card from your
hand.
