Stadium/Metal Cup/5

Reward:  2 and 29000

Strategy:  Use Petroleum or a trained Pirate against Seashell. After Seashell is defeated, 2 Cool Fires are ideal, as they are resistant/immune against all the elemental attacks from Dragonfly and Steampunk. In doubt, as usual, use Legends or Pures for any of these battles... (standard Pure is *very* effective against Steampunk)

At minimum, your dragons should be level 15.
