This is a good card to play when theres a particular opposing character you really want to get rid of this turn, especially if you have something that can take the hits like a champ think Goofy, Knight for a Day or Lumiere, Hotheaded Candelabra
As you dish out plenty of damage via Bogo and Tinker Bell, challenges, and your bevy of Songs, you can easily use Beast to strategically take out foes via singing songs that dish out damage and then readying to do it all over again, or run away with the game sometimes even in a single turn via questing, damaging, readying, and questing again
Cards that can ready other cards often have limits built in
Theres a lot of choices to mess around with these big card drops of certain classifications
Some help you generate lore while others can help you draw cards
Doing this later on in your Lorcana game, when you have plenty of cheap cards in your discard, is critical to getting this card to really work for you
