Zombies tribal with 3 win conditions, in order of priority:

• Combo (see below)
• Zombie swarm (all hail our Zombie overlords)
• Grimgrin commander damage

I have chosen zombies because I like the masters, and master-impersonaters:

• Zombie Master
• Diregraf Captain
• Death Baron
• Undead Warchief
• Lord of the Undead
• Cemetery Reaper
• Risen Executioner
• Mikaeus, the Unhallowed
• Adaptive Automaton

Unfortunately there are not enough zombie masters to go nova, like you can with the sliver tribe.

Combo pieces

• Gravecrawler + Grimgrin, Corpse-Born + Rooftop Storm : Infinite commander damage
• Diregraf Captain + Gravecrawler + Rooftop Storm : Infinite damage to target opponent
• Gravecrawler + Rooftop Storm + Vengeful Dead : Infinite damage to each opponent
• Cloudstone Curio + Geralf's Messenger + Rooftop Storm + any other zombie: Infinite damage to target player
• Cloudstone Curio + Gray Merchant of Asphodel + Rooftop Storm + any other zombie: Infinite life drain from each player
• Gray Merchant of Asphodel + Rite of Replication : 60+ damage to each opponent and a lot of life.
• Diregraf Captain + Gravecrawler + Phyrexian Altar : Infinite damage to target opponent
• Gravecrawler + Phyrexian Altar + Vengeful Dead : Infinite damage to each opponent
• Ashnod's Altar + Grave Titan + Nim Deathmantle : infinite colourless mana / infinite zombies
• Mikaeus, the Unhallowed + Triskelion : Infinite targeted damage
• Cauldron of Souls + Triskelion : Weak once a turn combo for 1 damage + other to the graveyard triggers.

Highlights and synergies

• 5 decent tutors for combo pieces: Demonic Tutor, Vampiric Tutor, Increasing Ambition, Liliana Vess, and Sidisi, Undead Vizier
• recursion for Rooftop Storm: Recall and Crystal Chimes
• A lot of forced opponent sacrifices sort of mitigates missing spot removal
• Mikaeus, the Unhallowed and Cauldron of Souls : non-combo sacrifices are less painful. Also best friends with enters/leaves the battlefield triggers, of which there are many in the deck.
• Glen Elendra Archmage + Mikaeus, the Unhallowed : counters anything but creatures
• Urborg, Tomb of Yawgmoth + Zombie Master : unblockable army
• Thespian's Stage and Vesuva can both copy Cabal Coffers (or something less exciting, need be)
• Akroma's Memorial: Is a craftsman's Sword of Vengeance for all creatures with equip: 0
• Entomb: Fetches Gravecrawler
• When Gravecrawler is exiled I can fall back to Relentless Dead, Risen Executioner, Reassembling Skeleton or even Havengul Lich.

Known weaknesses

• Zero spot removal (what should I replace? and with what?)
• No equipment for Grimgrin, Corpse-Born (what should I replace? and with what?)

I would like suggestions on how to improve the power level of the deck towards competitive levels, and how to mitigate the weaknesses.
