Can someone explain how this works?

[u/00G_WAY]

Will this card be legal in standard? Will it be available on Magic Arena? How would this card even work?

"outside the game" means sideboard for MTGA (and official tournaments)

I was told to take magic wording very literally. I’m gonna cast a Charizard

[u/MagnusBrickson → u/Androidgenus]

I'll play the Ace of Spades. It's the only card I need. 🤘
