Ashen Rider deserves a main board. Also, False Prophet is good with all your sac outlets.

Corpse Dance and Sidisi, Undead Vizier are fun to abuse with infinite mana.

Unburial Rites and Buried Alive for obvious reasons.

And finally, Necromancy, because it's instant speed grave hate at best, or another reanimation spell at worst.

Personally, I would cut the following Council's Judgment, Decree of Pain, Mortify, Yisan, the Wanderer Bard, Yavimaya Elder, Spore Frog, Reclamation Sage, Dragonlord Dromoka... There are better alternatives, some of which you're already running.

Some of your ramp spells could be replaced with cheaper variants such as Farseek or Three Visits. Although not ramp, I'm a fan of Evolution Charm.

neverdie Thank you for the comments (sorry I didn't reply earlier), I've been away from Karador for a bit, but pulled him out of the box again over the weekend and needless to say I'm hooked again. currently updating him, and definitely taking on some of your suggestions!
