Wargate is a Sorcery that costs X, Green, White, and Blue, and then allows you to search your library for a permanent card with mana value X or less, put it onto the battlefield, then shuffle.

My Umori/Old Stickfingers deck is a creature-only deck thats focused on graveyard value
Lorcana is newer, which means the ceiling is still forming
Mistmeadow Vanisher , a blink card that flickers things when you tap it
