Red decks these days have many tools to enable delirium, too
Its also a solid card for prowess decks, especially if you want players to take Monastery Mentor seriously
The highest rarities include Secret Ultra Rares like Ultra Necrozma-GX and Tapu Lele-GX, which appear in a golden full-art negative design
2B is a reasonable mana cost allowing it to be played in three-color decks, and its 3/2 body is perfect for applying early pressure or early defense as soon as turn two thanks to Gilded Goose or Llanowar Elves, while still being relevant later in the game thanks to its escape ability
Its role isnt flashy, but it is clutch
But having Shock, Raise Dead, Rampant Growth, or Preordain stapled to a Scry 2 when I am looking to sculpt my draws later offers more card advantage than most players would have known what to do with in 1993
