彈回碰上buyback跟flashback - 魔法風雲會

借標題問
之前玩Jace vs Chandra碰到的情況
對方出智謀Guile
{
Guile can't be blocked except by three or more creatures.
If a spell or ability you control would counter a spell, instead exile that
spell and you may play that card without paying its mana cost.
When Guile is put into a graveyard from anywhere, shuffle it into its owner's
library.

我flashback墳場中的巫術(火束)被對方counterspell

1.對方可以拿我的火束去用嗎?
2.假設可以拿去用,對方用完火束會去哪?
