Legolas, Master Archer's card doesn't say so, but it clearly works best with instants and sorceries, spells that often target individual creatures or two creatures at once
it wont work in Commander. But, looking at the mechanic, there was nothing problematic about it
Rowan, Scion of War is a cEDH level card with a much easier condition to fulfil (losing life) and access to X-spells that actually end the game
Bramble Familiar should be even better in Golgari decks that feature additional reanimation effects
Honored Heirloom Three-mana rocks arent as popular as they used to be, but grave hate is always nice
Even though Mathas, Fiend Seeker is unique and Licia, Sanguine Tribune deals with lifegaina fan-favorite Commander archetypeit's not enough for the Vampire deck to overcome the lack of numbers and get out of last place
