Bjorna, Nightfall Alchemist / Lucas, the Sharpshooter Goad is a great tool for Commander, but having that be the payoff for a sacrifice effect on a card that doesnt actually create any artifacts itself is a bit of a head-scratcher

Leyline of the Guildpact might not be the most powerful, but it gets the MVP award on this list because it fixes your mana in one card

Eevee - Colorless - HP70 Basic Pokemon [C] Nap: Heal 20 damage from this Pokemon [C] Headbutt: 10 damage
