QWhen selecting an Umamusume follower for "Give it and this follower Storm," can I select this follower?

AYes, you can.

QIf I play a Umamusume spell, then put Daiwa Scarlet onto my field on the same turn, does the next Umamusume spell I play that turn cost 1 less?

ANo. The next Umamusume spell you play would be the second one that turn.

QIf I have 0 remaining play points with Daiwa Scarlet on my field, can I still play a spell that costs 1 play point like Lamplit Training of a Witch-to-Be if it's the first Umamusume spell of the turn?

AYes, you can.

QIf I have 2 copies of this follower on my field when I play my first Umamusume spell of the turn, does it cost 2 less?

AYes, it does.

QIf I play an Umamusume spell during an opponent's turn, does it still cost 1 less?

AYes. If it's the first Umamusume spell you've played during that opponent's turn, it costs 1 less to play.

QWhen counting how many spells I've played this turn, do I count spells I played before this follower was put onto my field?

AYes, you do.
