For Sun Disc with Legion, can you use its ready effect the turn you play it, or do you need to play 2 units first?

Ruling: You can use Sun Disc's effect the turn you play it. Sun Disc itself activates Legion when played, so you can immediately tap it to ready a unit without playing another card first.

Sequence:

• Play Sun Disc (this activates Legion)
• Immediately tap Sun Disc to use its ready effect
• On subsequent turns, you must play any card (unit, spell, or gear) to activate Legion again before you can tap Sun Disc

Nuances:

• Sun Disc is different from other Legion cards that have "when you play me" effects - those require Legion to already be active when played, but Sun Disc activates Legion by being played
