EDH Advice

I have these two decks that I've been modifying for some time now, and id like to get some advice on how to speed them up and make them more resilient. One is black Zombie tribal with Lilliana, Heretical Healer for the commander, and the other is Angels with Giada, Font of Hope. here are the Archidekt links:

Any advice for bumping up the speed, consistency, or power of either would be most welcome.
