Even some of those little art cards you toss by the wayside when you're cracking booster packs are going for a pretty penny

Those cards that are somewhat more dependent on each other tend to be better for balancing the overall card advantage of Partner commanders, like Haldan, Avid Arcanist and Pako, Arcane Retriever

I almost shouldnt need to explain why thats absurdly powerful, but let me give you an example

8: Eutropia the Twice-Favored - Theros: Beyond Death There was not a lot of Theros: Beyond Death that really excited me, but Eutropia manages to do two very exciting things: (1) be deceptively powerful, and (2) be a Simic commander that is perfectly fair

If an effect requires you to pay some amount of mana to prevent Astelli Reclaimer from being countered, as Divert Disaster does, that mana wasn't spent to cast Astelli Reclaimer and will not be taken into account
