Commander Myriad - When Itachi Uchiha attacks, for each other opponent, create a non-legendary token copy that's tapped and attacking. Exile those tokens at the end of combat.
Whenever Itachi deals combat damage to an opponent, look at their hand. You may copy
an instant or sorcery in their hand. Cast it without paying the mana cost
