A · Fundamentals · §1
A token tempo deck whose entire board expires every turn, so every point it scores has to be a conquest.
Lillia Sprite Tempo makes 3-Might units out of Energy rather than out of cards. The Legend, the champion, one gear and two spells all produce the same token, and by the middle of a game most of what you control was never in your deck.
What separates it from every other go-wide deck is that the tokens carry Temporary. They die at the start of your own Beginning Phase, before scoring, every turn, without the opponent doing anything. The deck therefore cannot bank a board, cannot sit on a battlefield, and cannot wait for a better turn.

That constraint is not a drawback attached to an otherwise normal deck. It is the deck. It decides the mulligan, it decides which battlefield you fight for, it decides that a turn spent developing without conquering is a turn the Sprites were wasted, and it is the reason a permanent 2-Might body like is more valuable here than its statline suggests anywhere else.
