Deal [Magic + 4] damage to an enemy. If they are a Tower, deal 3x - 5x damage, based on my Ascensions. Gain 2 Mana, boosted by my Gold. [3:1]
Transform all Green Gems to Blue. Give [Magic + 1] Gold.
Scurvy Seadog gave gold, Red Charlotte gets all of its mana back on cast at 30 Gold. High level explore will meet that criteria easily.
