Very nice take on U/B landstill.

I really like some of your card choices (Haunting Echoes especially), however some choices seem really odd to me (namely Ghastly Demise and your "man plan").

I try to give some feedback on some card choices:

Playing Engineered Explosives with only two colors seems a bit suboptimal to me... why not play Powder Keg instead?. Most relevant enchantments (namely Solitary Confinement) are more expensive than 2 anyways, making that a moot point for Explosives.

Have you considered to add one or two Nevi Disks? Might be too slow, but can take out cards the deck wouldn't handle otherwise.

Stifle hot or not? A clear "the hotness". Stifle is so freakin' awesome, giving you the edge in a tempo based game (countering fetch-lands is huge).

Abyss hot or not? The Abyss is really weak against U/W/G Thresh, mediocre at best vs. Goblins (goblins want to overextend anyways to beat you down, so there's no point in forcing them to overextend with a 4 mana enchantment). A really goofy card, looking great on paper but actually doing far to less to warrant a deck slot.

I don't think I like 4 Counterspells in this deck, UU is a big stretch on the manabase (8 colorless lands... hard to support UU at most times). Counterspell is obviously a good card, but maybe 2 would be enough (replacing the other two with some other kind of permission spell, not requiering UU).
Possible options: - Disrupting Shoal
- Spell Burst (a big "if",I'm just brainstorming on these)
- Mana Leak

Ghastly Demise? Seriously? I think outside of U/B/G Thresh this card is too hard to use effectively. I would run either Edicts or Innocent Blood (sorcery - yes. but can hit that pesky mongoose, which Demise can't touch) in this slot.

As for Damnation, we all agree, that it's superior to Decree of Pain...

Sideboard:
I think the man plan simply wastes to many slots. That simple.

The 8 slots could be better filled with a mix of Extirpates and some Counterbalances// Sensei's Divining Tops. I played these for some time now and I am really impressed. Counter/Top wins games you don't have business winning. It's just so amazing against a wide variety of decks (I know this contradicts with the "UU for Counterspell is hard to get" argument).

Adding a third color is always an option that gives big rewards for a big risk.

Let's see:

I'll list just the most obvious cards...

White:
- Swords to Plowshares
- Vindicate
- Decree of Justice
- various Disenchant effects
...
kind of meh... If considering these, why not simply play U/W Landstill...

Red:
- Burn (Lightning Bolt, Fire//Ice)
- Pyroclasm or Rough//Tumble (does this deck really need more creature kill?)
- good Artifact hate
- nice sideboard hate vs. white and blue

Green:
- Pernicous Deed (Now that's better than Explosives)
- Regrowth (might turn into Demonic Tutor mid- to lategame, really huge if revealed with Fact or Fiction)
- Krosan Grip (uncounterable Enchantment and Artifact hate can't be that bad)

Sweet.


I think of the above mentioned options, if any I would probably settle with Green... Looks to be the most powerful. Deed >>> Explosives/Keg/Disk.
