Can you use the Shard to reduce the cost of a canceled that that is still paid?

Minion A plays a combat card that cost 2 blood, annoucnign to use the shard on that card
Minion B plays botched move and the same combat card comes up. the comabt card is therefore canceled, cost is still paid.

As Cost reducers are not locked, when the card they are used for is canceled, the shard stays unlocked.
But Minion A ahs to still pay for the card, as botched move does not says "cost is not paied" (in fact is hat remidner text that cost is still paid)

Can I still use the Shard to reduce the cost of the card?
