mtg ixalan booster box Magic The Gathering - Lost Caverns of - Set But outsiders—first the treasure Caverns Of Ixalan Set Booster
Description
This can only be activated at sorcery-speed, still this is a powerful ability
If instructed to search for a planeswalker card or for any card, you could find yourself (literally as well as spiritually)
When you cast instants and sorceries, the Devils get +4/+0, which can add up pretty quickly
This is a good way to avoid an opponent's removal or burn spells, and pump your creature at the same time
