Kalista, Spear of Vengeance

Fearsome - Kalista can't be blocked by creatures with power 2 or less

Whenever Kalista attacks create a tapped and attacking token that’s a copy of a non-legendary creature with the highest power among creatures in your graveyard except it also has the text: "if Kalista would take damage i take that much damage instead " and is a spirit in addition to its other types. Exile that token at end of combat.
