Warden of Evos Isle

Text:

Flying
Creature spells with flying you cast cost less to cast.

Rulings:

• 11/10/2020 A creature spell that doesn’t have flying won’t cost less even if an effect will cause the creature to have flying once on the battlefield. This is also true if the creature spell itself has an ability that gives it flying once on the battlefield under certain conditions, even if those conditions are true.
• 11/10/2020 The last ability of Warden of Evos Isle can’t reduce the colored mana requirement of a creature spell with flying.
