I would add Prophet of Kruphix

Cool, thanks for the suggestion. What would you pull?

I'm not sure maybe Tromokratis or Horizon Chimera but you have played this deck a lot more than I have so you know best.

Whatdya think of Nylea's Presence to cap the Chasm Skulker win con and also draw an extra card AND mana fix a bit?

I really like Bident of Thassa because most of the time I'm able to attach him to Hydra Broodmaster or Chasm Skulker and get to draw two cards right away. Also, Kruphix, God of Horizons works really well with Life's Legacy because otherwise I'm usually discarding with it.

Went 2-1 at a three round night at the local game store. I was running RUG then, and I think that contributed to my first round loss to B/G. If I had more consistent performance (i.e., more stable drawing without mana concerns and more repeated effects with those cards) I probably would have won. Chasm Skulker is a blast to play, and people frequently let him get out of hand without even realizing it. I strongly suggest trying this deck. It's a fun one even when you lose.

Placed second at last night's (8/15) FNM. Won against B/W life gain and mono black control/devotion. It lost to mono-red rabble aggro. Couldn't stabilize fast enough. Maybe Hornet Nest? There's so many triggers here that you got to pay a lot of attention. In a turn I'd be tripping three +1 counters on the Skulker, gaining two life from a land play with two Coursers, and three life from the Horizon Chimera, while forcing them to discard their best creature put on top of their library due to Aetherspouts and Dakra Mystic. It was wacky.

Hydra Broodmaster works really well. Even if you only get him to a 10/10. It's still not bad at all and you can always use Life's Legacy on him. 2 Chasm Skulker s that are like 15/15 isn't half bad at all. Also Ordeal of Thassa is great. Usually draw 2 cards for 2 mana

my thoughts for adding black would be to drop the elvish mystics, and courser of kruphixes, and add 4 Dictate of Kruphix and Fate Unraveler seems like it could be fun to gain life with the chimera while your opens loose life.

I dig it. Fate Unraveler seems a tad slow for my needs. Also, 4 Dictates is a LOT of card draw for them. Maybe 2 Unravelers and 1 Dictate of Kruphix... but i like your suggestions so far. What DO you think of the Stockpile?

I've been looking at it for a while, my thoughts about it is that it needs zombies to be truly worth it. Last thing you need to do is empty your hand of creatures to replace them with lands and a couple support cards. At least discarding creatures for a creature and a card in hand is worth it. But discussing Dictate of Kruphix thing, think about that card draw for your opponents, a Tormented Thoughts on your chasm skulker late game with a waste not on the field (of course you'll have these with the card draws haha) can easily be a game winner... I might go brew up an idea

It's why eight of the win cons have Shroud. :-P The goal is to aggressively mulligan until you've got ONE land and Quest for Ula's Temple in your opening hand, and then you drop Krakens from turn 4 onward. Any counters would also alleviate the effectiveness of burn (which doesn't show up in my meta anyway). Disperse wouldn't work because it would just undo the work I'm doing anyway.

I have a forum with suggestions open, and people have suggested- Judge's Familiar, Dispel, Spellskite, Spell Pierce, Remand, so on

Oh, no, I'm fine with comments here, I'm just saying that there's a place where people are making suggestions you haven't seen

You need more lands, an average cmc of 4 with 16 lands doesn't work very well.

If that's your advice, you're just trying to pump your rating by leaving random comments, since you clearly did not read any of what my deck does.

I did read your description. You need at least another 2 or so lands, because your plan a won't always work.
