I think the best part of this is that you could target your stuff, or your opponent can, and you still get the benefit across all your creatures
Nowadays, youre a lot more likely to see a creature such as the not-so-subtle reference of Ravenous Giant in the Uncommon slot
This one should really spike in price to about $30 a piece, and if suddenly Alrund's Epiphany gets banned in standard because of their interaction, then expect it to level down to about $15-20 range
Ill be using my own decks as examples, as well as decks from my regular playgroup Now, this isnt to say that everyone should have seven decks I know thats not financially possible for everyone
You can also look to leverage spells which implicitly allow cooperation between different players, such as Discerning Financier, the various curse-type auras, voting spells and similar effects like Councils Judgment or Lavabrink Floodgates, and damage redirectors like Stuffy Doll or Brash Taunter
That's the big one, clearly the main reason for why WotC is jumping through so many hoops here, and it's really huge: It keeps Arena and MTGO metagames aligned with tabletop, and it makes Standard a format thats playable on all platforms
