What about Reflecting Pool? So many dual colored lands it should work. Doesn't cost life to tap.
I've never invested in a Reflecting Pool, as it doesn't fix a color that you might be missing in certain situations. I've always been a fetch-land into duel lands, with the 5-color lands that deal damage almost having no downside in 40 life commander. I guess sometimes it's just a preference thing.
What about Underrealm Lich for the cycling? The only downside I really see is the fact that it cost 5 instead of 6. Lets you control draw better and feed the graveyard.
I really love your deck brew. I tried a few test plays and thought it was fun in a way I don't usually play. I was wondering a few months ago how to use Astral Slide in a fun way.
I might have missed it, but can you get Astral Slide with Bring to Light?
Fair enough. After playing a few times I made a few changes. Kaervek the Merciless has been fun and I am trying to decide between Deadbridge Chant and Pharika's Mender to round out golgari as I removed Gleancrawler. Also fun thought is that the Gods count as creatures in the hand and graveyard so some of them could work nicely. Specifically Xenagos, God of Revels, Mogis, God of Slaughter, and Iroas, God of Victory. To a lesser extent Ephara, God of the Polis, Keranos, God of Storms, Phenax, God of Deception could also be options.
