Baragon, Mage-Rager

Haste
When Baragon deals combat damage to a player,
search your library for a sorcery card and that player
searches their library for an instant card.
Then you and that player each flip a coin
If you win your flip, you may cast the
sorcery spell without paying its mana cost.
If the other player wins their coin flip,
they may cast the instant card without paying its
mana cost.
{r} Baragon gains +1/+0 until end of turn.
