Can Tetto'ekos IF-ability be used every turn or just once? (can't remember the name, but it's the one which makes all lore of heaven spells IF on any double)
You're talking about the Herald of Cosmic Events rule? It says it is rolled for at the beginning of any one friendly Magic Phase, so I would venture to say that it is a one-time use thingy.
Ah okay. Darn. I wasn't sure since english isn't my primary language, so wasn't completely sure if it meant only one or if you could just pick any one (meaning that you didn't had to use it every turn). But that makes him quite expensive for what he does ..
