Wizards of Thay — Battle for Baldur's Gate Promos #105s

Myriad (Whenever this creature attacks, for each opponent other than defending player, you may create a token copy that's tapped and attacking that player or a planeswalker they control. Exile the tokens at end of combat.)

Instant and sorcery spells you cast cost less to cast.

You may cast sorcery spells as though they had flash.
