Are there any viable replacements for Kodorider and Sylvanas Windrunner? I either have or can probably substitute for the rest, but I haven't seen any suggestions to replace those two.

Sylvanas could probably be replaced by something like a Piloted Sky Golem while we're still using Wild format, especially considering many times Sylvanas is silenced or played around. If you don't have Sky Golem, Cairne Bloodhood might also be good, but nowhere near as strong. 

I think Kodorider is sort of hard to replace because it's one of the best cards in this particular deck. Most of the time it gets killed right away, but if it doesn't you basically either win or cost the enemy a ton of resources. You could always just a different similarly costed strong card like Dr. Boom, but there's nothing really similar to Kodorider to replace it with. 

This, of course, is Kibler's deck and these are my personal recommendations for substitutes. Admittedly, I'm not a great deckbuilder so there may be better substitutes out there. You could always try a few different substitutes things and see what something works.

Looks good, but how about a Youthful Brewmaster for 2x reno value?
