This version of the deck seeks to abuse the interaction between Bitterblossom and Skullclamp. The rogue generator loyally pumps out tokens ready to be clamped for card advantage.  I feel this version is better positioned to afford the flashback of Cabal Therapy so the discard suite it tweaked slightly.  Against storm combo decks there is the ability to up this suite by siding in the Hymn to Tourach. There is a slight tweaking of the manabase to reflect the higher proportion of black cards, and likewise Elves of Deep Shadow get bumped to 4 of. 

By keeping the green this version gets to keep the powerful Tarmogoyf and the versitle Krosan Grips.  The Essence Warden is even more useful in this build, helping to negate the continual damage spent in the course of making 1/1 fliers.  The Bitterblossom also offers an "out" to Moat.

I think it might be necessary to downgrade the Thoughtseize to Duress especially since the blossom is hitting the life resources.

Finally I could not resist the chance to play Oona's Blackguard it can take a clamp and net you 2 cards, but more importantly is the interaction with Bitterblossom.  The fact that it also has flying is a nice added bonus, there are not all that many flying creatures in classic at the moment so this evasion is normally good for inflicting some damage.

Finally I offer my MonoBlack take on Bitterblossom. The Dark Ritual allow this deck to inconsistently get off to an amazing start, either busting out a Hypnotic Specter, pairing up some discard spells, or dropping a blossom and a clamp.  Being mono-black this deck losses out on the mana elves and I personally prefer the consistency of the green black builds.

There is lots of pain in this deck and it is a big gamble to run Dark Confidant and Bitterblossom.  The Confidants can be off loaded with clamp of course once life totals become critical. The Stromgald Crusader again add a flying threat to the deck and can be pumped late-game, their ability to dodge Serra Avenger, and Swords to Plowshares should also not be underestimated.

The sideboard is similar to the other decks but the lack of green removes the excellent Krosan Grip and blacks lacks any suitable replacement. The other card of note is Abyssal Gatekeeper this is being tested as away to remove thresholds Nimble Mongoose and is also useful against true aggro matchups.  The Gatekeeper interacts fine with the cabals and the clamp, and I have even considered moving the Gatekeeper to the maindeck.

Although this deck has potential I think it too often just gets an average start.

I hope you have enjoyed this look at how Skullclamp can impact on Classic. I recommend you pick up a playset of this uncommon and start making some fun competitive classic decks. If you already own Tarmogoyf and Bitterblossoms as part of your extended or standard collection then it is relatively inexpensive to acquire the cards to fill out a classic deck and come and join the classic gamers in the Tournament Practice Room.

Thanks for reading.
