When Dáin enters, create a colorless Equipment artifact token named Axe with "Equipped creature gets +1/+0" and equip (: Attach to target creature you control. Equip only as a sorcery. This card enters unattached and stays on the battlefield if the creature leaves.). When you do, attach it to target creature you control. Whenever Dáin attacks, each equipped attacking creature gains double strike (This creature deals both first-strike and regular combat damage.) until end of turn.
