cycle seems like it is designed for limited, but grandeur is a very weak mechanic for limited. this could be flame wave and it would still be weak
I like this idea. 1B won't be too bad as it would be a two card pyroclasm. Just make the Grandeur ability at sorcery speed. 1B for deathtouch would also be a fine card in limited. I think this is well designed.
The reason I gave it the 2B cost is I don't want it picked highly. The grandeur cards work well if you can get a few of them, and the fact that it should go as a later pick to most people makes it a powerful card if you get a few. If one person picks all of a specific grandeur card in one draft, they could feasibly have 5 or 6 in a draft deck.In sealed, though, it's probably hanging out on the sidelines unless you get 2.
