Neon Dynasty flips this around a bit by having sagas specifically reference cards from the old Kamigawa set
Card Name Vaan, Street Thief Mana Cost Type Legendary Creature Human Scout Rarity Rare rules Text Whenever one or more Scouts, Pirates, and/or Rogues you control deal combat damage to a player, exile the top card of that player's library
You have to play it, wait a turn, then attack, hope it survives to get a second use, and have a card in hand worth having the cost reduced
And are they worth hunting down through the special Pokemon GO set's limited-availability expansion packs
Alongside ol' Ray, the expansion also includes new Mega ex cards for Metagross and Gallade, and a particularly fetching Dragonair full art
At worst you get a few fetch lands back and never miss a land drop
