Excuse?
Horakhty looks VERY interesting as a wincon, but I'm too lazy to brew something that wins with it (why not just combo into card advantage, right?
).
Inti/Quilla is too easy to stop, by the way - it's alright I guess, but it doesn't have very much impact upon the board either and you probably wasted a bunch of advantage to summon it, so it's not worth it.
