You need to get Terminate. It will bring them into Haunting range easily. Also I'd reconsider Mind Funeral, milling 10-12 cards isn't worth 3 mana (tome scour/Glimpse of unthinkable value milling at 5 cards per mana) PtE/Archive combo is probably unnecessary tho it is nice if you have the space (you can fit it into 60 cards). You can probably remove negate/countersquall/essence scatter, PtE/cancel/agony warp can deal with most threats that get through silence effects. Get 4 exhaustion to run next to your 4 silences. Nemesis probably should be included just in case you don't pull a haunting echoes/terminate. I agree with running crabs because they are 1 drops so every land drop will mill, maybe get sac lands or fixers for them.

I couldn't help but post when I realized it would be bloody hilarious if you could somehow get Prince of Thralls into play. Yes, i realize its mana cost is too steep to be reasonable, but being able to play 13 of your opponents cards is just too funny.
Nihilith would work to pull all of the suspend counters off. Also Bloodcheif ascension is the effect your looking for (as already mentioned.); you have to find a way to get some quest counters on it tho. Inkfathom Infiltrator could get those stacks, also Sleeper Agent is viable if your willing to give them a 3/3 (vampiric link, pillory of sleepless, pacifism could easily render it useless to the opponent).
