Let me start from the basics.

1) this card is a Resona, so it is placed in your Lrig deck instead of your main deck

2) this card can be summoned during your main phase as long as you satisfy the play condition

3) the play condition of this card is to put 3 of your non-Resona space type signis from your signi zone into trash, and then you can summon this card from you Lrig deck

4) when this Resona is summoned, you can use its [On-Play] ability and send 1 of your opponent's signi to trash

Hope this helps.
