Wol [Emissaries of Light]

The cost required to cast Wol is reduced by 1 for each Character of cost 5 or more you control (it cannot become 0).
The Forwards of cost 5 or more other than Wol you control gain "This Forward cannot be chosen by your opponent's Summons or abilities."
When you cast a Character of cost 5 or more, draw 1 card. This effect will trigger only once per turn.
