If were doing that, Im going to add the 12 Astral cards from the old PC game, commonly known as Shandalar for 7,379
While fog cards like this aren't necessarily going to win you the game, they can cheaply give you the breathing room to win later.

Vanguard of Brimaz isnt great, but it works well with the sideboard devotion plan and works well with Ephemeral Shields which Im trying to incorporate in a more serious way in this deck
This was an additional way to show off the world of Ikoria, which ended up working out in some cool ways I'll get into later
Green does have a reputation for having the biggest and best creatures, after all
