Aurora

Aurora is the NPC that takes you to the Canada Day Campaign. It is also an unlockable Mega Card. It is obtained in the Canada Day Campaign.

Strategy
As the only troop that cannot get severely damaged by ranged troops, with her high DPS, she can easily grind through tanks and swarms, making her a viable Mega Card.

Her expensive cost is threathening to your towers, so make sure to defend by using a cycle card on the opposite lane on where you've put Aurora.
