If I was going to replace any of these cards I would do so for more draw. Cards such as Acolyte, Loot Hoarder and Thalnos could be more beneficial, Thalnos more then others. Additionally I use Yogg as an ultimatum, when all else fails (I think the only way you can use him. If you remove Yogg I would suggest an extra Flamestrike. The one card I want to try out if the secret "mana bind", I think it has a lot of potential.
