Voar
As mágicas de criatura com voar que você conjura custam
a menos para serem conjuradas.
Toda vez que outra criatura com voar entra no campo de batalha sob seu controle, Observador das Esferas recebe +1/+1 até o final do turno.
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.
