Beyond Boosters provide a curated opening experience for fans, with 7 Magic cards and 1 token/ad card or Art Card (Art Card in 8% of packs) in each pack
If your opponent discards a card while you control Leyline of the Void, abilities that check whether a card is discarded (such as Hollow One, or a madness ability of the discarded card) still work, even though that card never reaches that player's graveyard
This allows for a slew of A/B combinations between Doctor and Companion, each with a potentially unique color identity and mechanical theme
Scry plus proliferate is the way Ill be going here in order to get the extra turn
My Verdict: If you want fun, awesome art, and a standout collectors item , Aetherdrift is a must
Once again, playing cards for free is a great reward
