Grave Danger (SCB).
A Dimir zombie deck from the Starter Commander Decks, led by Gisa and Geralf, fill your graveyard with zombies and cast them directly from there, building a recursive undead army that never stays dead for long.
The Commander
Grave Danger is the Dimir zombie Starter Commander precon, and Gisa and Geralf run one of the most straightforward graveyard engines in Commander. When they enter, you mill four cards. Once per turn, you can cast a zombie from your graveyard. That's the whole plan: your graveyard is a second hand, and every zombie that dies drops right back into the pool of cards you can cast next turn.
Gisa and Geralf fold two of Innistrad's best-known necromancers into one commander, and they play out the whole Dimir zombie plan: mill, fill, cast again. Rooftop Storm is the biggest payoff. Once it resolves, casting from the graveyard costs zero. Havengul Lich gives you a second cast-from-graveyard engine for non-zombie creatures, and Death Baron and the other zombie lords make the recurring army much harder to face.
Key Cards
Rooftop Storm
You may pay zero instead of a zombie spell's mana cost. In this deck, that means the commander's graveyard-cast ability costs nothing, so you can cast every zombie in your graveyard for free in one turn. Add a death trigger that sends zombies back to the graveyard, plus Gisa and Geralf casting them again next turn, and Rooftop Storm becomes an effectively infinite loop of free zombies. The deck is built to find this enchantment as fast as it can.
Death Baron
Other zombies you control get +1/+1 and deathtouch. A deathtouch zombie kills anything it blocks or fights, no matter how big. In a deck that routinely fields twelve to fifteen zombies, Death Baron turns a wide aggro board into one nobody wants to block. Opponents can't trade profitably with any zombie, so your attacks get through. It's the deck's main lord and the difference between a zombie swarm and an unstoppable one.
Havengul Lich
Pay one mana to cast a target creature card from any graveyard until end of turn, and Havengul Lich gains that card's activated abilities until end of turn. Unlike Gisa and Geralf, it reaches into any graveyard, opponents' included. For one mana you can steal the best creature in an opponent's bin. Against creature-heavy decks, that turns their own threats against them and pads out your zombie army at the same time.
Open the Graves
Whenever a nontoken creature you control dies, you make a 2/2 zombie token. Every zombie that dies becomes a new one. In a recursive deck where zombies are constantly dying and getting recast, Open the Graves keeps the headcount from dropping. Combat, sacrifice, removal, each death spits out a fresh body. Pair it with Rooftop Storm and the free tokens set off other death effects, so the army rebuilds faster than any single board wipe can clear it.
Army of the Damned
Make thirteen 2/2 zombie tokens, with flashback for eight mana. Thirteen zombies from one card overwhelms almost any board. Give them deathtouch with Death Baron and nobody can block them profitably. Flashback lets you cast Army of the Damned twice, so that's twenty-six zombies over two turns, plus whatever Gisa and Geralf keep adding from the graveyard. It's the deck's main way to win from an empty board.
How to Play
Mill hard through Gisa and Geralf's enter trigger and whatever blue mill spells you draw. The faster the graveyard fills, the sooner the engine gets going. Land Death Baron early for the deathtouch pump, and opponents who can't block profitably stop attacking into your zombies. Rooftop Storm is the enchantment that wins games: resolve it with four or five zombies in the graveyard and cast them all for free in one turn. You win on attrition. The army rebuilds every turn off Open the Graves replacements and Gisa and Geralf's graveyard casts, and Army of the Damned floods the board again whenever the game stalls.
