This is an evolving topic, more cards may surface and change the information above
Because promos ship in sleeves or boxes rather than packs, surface condition out of the gate is usually good but always check before assuming gem-mint
For example, Strionic Resonator can copy your enter the battlefield abilities of cards with initiative like Caves of Chaos Adventurer Since youll be using cards like Xanathar, Guild Kingpin to play cards from your opponents, theres a slight chance that you run into cards that can venture into the dungeon even before you get the initiative, (maybe you snag a Nadaar, Selfless Paladin, for example)
If you can build a deck whose only nonland permanent is Omniscience, you can cheat it out with ease
All cards come near mint conditions you will get mix of 10 cards no energys at all can be a mix of trainers/commons/Uncommons & your guaranteed a rare/rev/holo or v/vmax card in each pack if you order bigger packs you will receive more and also no duplicates
