Speaking of Oona, have you tried out the new Dramatic reversal + Isochron Scepter ? From what I can tell its pretty powerful with her.

It does look interesting but those are pieces (+1 mana rock) that don't exactly synergize well with the rest of the deck. They are also hard to recur and I can't think of ways to assemble it aside from tutoring every single piece. I can probably find a way to put it in the deck but that will require a lot of restructuring. Not sure I have the time and budget for that especially now that i'm building a leovold deck of my own.

Why tidespout tyrant? Seems an odd fit when the curve is already on the tubby end of typical ad-naus territory... is it a backup dread return target or something?

Good work though. I like this better than the mesmeric orb backup ive seen in HD sidisi.

Tidespout Tyrant is the only creature in my color identity that can win the game against an entire table with Food Chain combo. The full sequence is described in the bottom tab. Being an 8 drop hurts, but not enough to not include it. My tubbiness actually comes in handy with Necrotic Ooze combo too :-) with three primary combos I rarely have to dig as deep as most Ad Nauseam decks to get my game ending combo too.

would Gitaxian Probe and/or Peek be worthwhile in the deck to possibly see what they have in their hand before you combo off?

Definitely Gitaxian Probe since it also allows me to make a mini Doomsday pile of sorts with Memory's Journey if my plan A hermit druid gets shut down, but finding room is always the issue. I'll add it to the sideboard.

Ever run into mana issues with only 30 land?

Not often, but 1-2 more lands wouldnt hurt the deck. I mulligan pretty aggresively and also have the ability to drop a turn 1 Sylvan Library or Necropotence somewhat frequently and include cards like Ponder to dig deep on turn 1. If your not comfortable going so low you could always cut Intuition, Dark Confidant, and Lotus Petal.

ever think of replacing Fatestitcher with Prized Amalgam?

_person_: If this was a graveyard centric zombie build that was looking to grind value out of free creatures and/or turn sideways for the win I would, but in this deck Fatestitcher will always get me a creature in play for Dread Return and then untap the land I used to unearth it, whereas amagalam is only good for me IF I mill it before Narcomoeba.

I think that the hermit druid will resolve completely before any triggers can go on the stack.

Actually, he is right. The whole ability resolves before anything triggers. Additionally, everything technically enters the graveyard at the same time. They are not milled, but rather set aside until the resolution is complete. It is more of a back up incase someone shoots hermit druid before your creatures enter the battlefield from the grave.

Wow thats good to know. My bad and thank you for pointing that out. The only reason I can see for continued use of fatestitcher over amalgam is that IF narcomoeba gets stuck in my hand I get nothing. I am running a ton of 1-2 drop creatures in the deck so rather than include both I am depending on mana dorks to fill that backup creature role. Either way its a very good suggestion. Thank you :-) I'll do some testing and perhaps make a change.

In other news, after playing around with Chord of Calling in other builds I am tempted to replace Intuition with it. Intuition is kind of an awkward fit and being able to sneak HD in on my opponents end step is pretty sexy. Thoughts?

Chord of Calling seems extremely mana intensive. Not to mention what would you search for it to win? Another Hermit Druid search? Intuition is another possible Necrotic Ooze combination grabber at instant speed.

I feel like chord is great because you can also search up your necrotic ooze if combos are in the grave already. also, instant speed hermit druid is awesome.

They are both great cards. I think Intuition is a better card, but instant speed HD is really nice and it synergizes better with cheap creatures.

Absolutely BEAUTIFUL list. Well done! Have you considered Riftsweeper as an option for recovering flashbacked pieces should things go wrong?

CivilizedSin: Thank you bro! I spent more time on this list than all my other lists combined. It taught how to play cEDH. It will always be one of my favorite decks. I have not traditionally been a fan of Riftsweeper effects for this deck due to my concentration of win conditions but I will definitely consider it going forward

You've actually convinced me to update my Sidisi list to take this route. Currently I'm running the midrange horde-based strategy with some combos as backup, but this looks soul-crushing to play and I love it. I think I'll have to redirect some of the cards to a second Grimgrin, Corpse-Born EDH deck, but I thank you wholeheartedly for the inspiration.

You are most welcome :-)
