Banshee of the Dread Choir

Myriad (Whenever this creature attacks, for each opponent other than defending player, you may put a token that's a copy of this creature onto the battlefield tapped and attacking that player/a planeswalker he/she controls. Exile the tokens at end of combat.)

Whenever Banshee of the Dread Choir deals combat damage to a player, that player discards a card.
