At least you do have to risk something to get what you want
Led by Quintorius, History Chaser, a planeswalker , this deck is built to generate spirit tokens and isn't afraid to let cards head to the graveyard because there are ways to either cast the card again (Flashback) or, in the case of creatures, bring them back to the battlefield
You would take half with Gisela out, so just a single damage per nonbasic land you are running, while your foes double, so essentially four damage per nonbasic land they control
This makes Six an effective way to use your entire graveyard as extra cards in your hand
Yes, the front half turns your legends into mana dorks, but no one ever casts Esika
