1mana monsters

I wouldn't doubt if masa was being sarcastic. I've mentioned that same ability for Gremlin about 3 times now; it's pretty much a joke at this point.

Generally you want something that's spell/ability immune to be able to take advantage of those conditions. Immunity on Skyrian seems like a nerf as generally your opponent isn't going to waste spells on it and save it's abilities for just about anything more threatening. I guess you could argue that spell/ability immune Skyrian + Shadowforce Heart would be a good combo.
