How it works
Cast Crimson Kobolds by paying its mana cost.
When Crimson Kobolds enters the battlefield, Intruder Alarm triggers, untapping all creatures.
Activate Tradewind Rider by tapping it, Crimson Kobolds and one other creature you control, returning Crimson Kobolds from the battlefield to your hand.
