Torrent Sculptor // Flamethrower Sonata

Ward (Whenever this creature becomes the target of a spell or ability an opponent controls, counter it unless that player pays .)
When this creature enters, exile an instant or sorcery card from your graveyard. Put a number of +1/+1 counters on this creature equal to half that card's mana value, rounded up.
//
Discard a card, then draw a card. When you discard an instant or sorcery card this way, Flamethrower Sonata deals damage equal to that card's mana value to target creature or planeswalker you don't control.
