Starts at 4/4) 0: One 3/3 (Huatli, Warrior Poet) -1: One 4/4 (Vivien on the Hunt) 6-mana: +1: One 2/2 with major upside (Vraska, Relic Seeker, Ugin, the Ineffable, Liliana, Dreadhorde general), three 1/1s (Elspeth, Suns Champion), two non-defensive 3/1s (Chandra, Flamecaller) 0: Two 2/2s with minor upside
Curiously, despite being more expensive, Witch-king, Bringer of Ruin isnt the more synergistic card out of the pair
