Paranoid Delusions, Helm of the Ghastlord and Talent of the Telepath could all help out.

Mundungu is just fun.

Spreading Seas draws a card and changes a useful land into islandwalk/swampwalk hilarity

I wasn't sure as much about paranoid delusions when I saw it, but now that I look again I might want to add it to the sideboard for matches with less creature destruction.

Helm of the Ghastlord seems good, though i'm a bit hesitant about the cost.

I've already got spreading sees, the landwalk and cantrip are fantastic!

Mudungu is a nice free tempo every turn cycle, but it's also single target and very susceptible to removal (being a 1 toughness creature).

Thanks for the suggestions!

Woops, I also missed the comment about Talent of the Telepath. I sideboarded it because I wasn't sure what to cut, but I might move it back in if I can find something better to cut.

I like this list, definitely going to try out some cards with my build I'm working on. I love Crypt Ghast, but is it legal in this deck given the white mana symbol in its extort cost?

Atticustpr, strangely enough it is - the white symbol is in reminder text, which does not count towards color identity. Glad you like the list!

This changes everything. Thanks for that tidbit!

No. The explanation of "Extort" is specifically given as a case when the mana symbol on the card does NOT allow its use in commander. The mana symbol is not actually part of the card, it is only part of the explanation.

omg sorry. i read that backwards. Yeah since it is NOT part of the card it is legal in a deck with no white mana in the color identity. it was a long day at work, sorry
