one pack of pokemon cards TCG 3 Booster Packs, 30 Total, Value with 3 Blister Packs, 100% Authentic, Random Chance at Rares & Holofoils : Toys & Games Each pack includes 1 guaranteed holo rare card Pokemon TCG: 1000 Assorted Cards

Sarkhand, Soul Aflame reduces the cost of all your Dragon spells by one generic mana while in play, making it an auto-inclusion in just about every Dragon commander deck that can play it

It provides space for 360 cards (even double-sleeved)*

Its extremely good but in an entirely different way from something like Uro, Titan of Natures Wrath

Teferi, Master of Time Teferi, Master of Time is a beast in Commander

Although a well played Ben Beckmann can easily get around that

Authority as an ability would be pretty useful on a creature, definitely not sure if that'd be more printable than Pro-Weenies as you originally posted, but it'd be a nice ability that ends up feeling fairly simple/straightforward
