Flash + Fling - 魔法風雲會

Flash {1}{U}
Instant
You may put a creature card from your hand onto the battlefield.
If you do, sacrifice it unless you pay its mana cost reduced by up to {2}.

Fling {1}{R}
Instant
As an additional cost to cast this spell, sacrifice a creature.
Fling deals damage equal to the sacrificed creature’s power to any target.

我可以用Flash放一隻生物進場，
不付(或付不出)他的mana-2的費用，但是用fling犧牲他以造成傷害嗎?
