Artoria, King of Knights

Eminence — Whenever you attack with one or more Knights, if Sidar Jabari is in the command zone or on the battlefield, draw a card, then discard a card.

Flying, first strike

Whenever Sidar Jabari deals combat damage to a player, return target Knight creature card from your graveyard to the battlefield.

"From this time forth, my sword shall be with you."
