On the card it reads:
"Fellella can cast only enchantment spells."
From the rulebook:
"All enchantments have two mana costs on the card. The first cost, next to the closed eye, is the casting cost that you must pay when you cast the spell... The second cost, next to the open eye, is the reveal cost..."
When you cast an enchantment spell with Fellella, can you also pay the reveal cost with her mana counters?
