Riftbound Legion: what it does
GlossaryLegion is a Riftbound dependent keyword that rewards playing more than one card in a turn. "[Legion][>] [Text]" is short for "if you've played another card this turn, this card gains [Text]" — the bonus text is dormant until you've finalized a second card on the same turn, then it switches on for the rest of that turn.
How Legion turns on
Legion checks for a DIFFERENT card than the one with the Legion ability having been played by you earlier in the same turn. The moment that's true, the Legion text becomes active for the rest of the turn — it isn't a one-time trigger, it's a condition that stays satisfied once met. If you control several cards with Legion abilities, playing just one other card that turn turns all of them on at once.
Building around Legion
Legion rewards a deck built to play multiple cheap cards per turn rather than one expensive one — cheap units, cantrips, anything that gets a second card down early so your Legion payoffs are live for the rest of the turn. It shares a build-around shape with Level and Hunt: all three ask you to hit a threshold rather than resolve a single effect. See the Growth Keywords guide for how they compare.
