Major Powers are a kind of Power Card that Spirits can gain over the course of the game to give them new options for dealing with Invaders. Compared to Minor Powers, Major Powers cost more Energy to use, but in return, they have more impactful effects on the targeted land or Spirit. Major Powers are useful on Spirits that gain at least 3-4 Energy per turn, and on Spirits that are less reliant on their Innate Powers. Unlike Minor Powers, after gaining a Major Power, you are required to Forget a Power Card in your hand, discard, or in play, if you're gaining a Major Power outside of the Spirit Phase. Including all expansions, there are currently 66 Major Powers in the game.
