The celestial hurricanum states that a wizard tending it can cast 1 spell during the hero phase. It proceeds to list the 2 standard wizard spells and adds comet of Cassandora as a third. Do people interpret this to be in addition to the spells a wizard already knows and can cast? For example, could a life wizard on the hurricanum cast 2 spells in the hero phase with access to Mage bolt, mystic shield, comet and lifebloom?
On the warscroll it's clear that a wizard on hurricanum only knows 3 spells
"A wizard tending a Celestial Hurricanum
can attempt to cast one spell in each of
your hero phases, and attempt to unbind
one spell in each enemy hero phase.
He
knows the Arcane Bolt, Mystic Shield and
Comet of Casandora spells."
Also on the warscroll, it's obvious that a life wizard would not be flufyf, or I'd say valid to put a life wizard on the hurricanum
"Some Celestial Hurricanums are tended by
Celestial Wizards."
