Rakshasa Vizier Rakshasa Vizier is a very simple demon that grows when cards are exiled, nothing more, nothing less
It gives incredible inevitability to the deck, particularly against the slower more controlling lists
Most of them are cheaper cards that are priced at $0.10 or less due to their lack of general playability
Now, if you have a Skyclave Apparition or similar card that can exile the Sun-Crowned, thats definitely worth bringing in for games two and three
The sneakiness of replacing itself while benefiting opponents too makes it a unique counter worthy of Blue's bag of tricks
Delve has been printed on creatures, instants, and sorceries so far, and we could see it on other permanent types in the future, but Teval, Arbiter of Virtue gives it to all your spells
