Shark Shredder, Killer Clone

A 4/4 first striker for four is a structural problem in a format whose common creatures cap out at 2/3 and 3/2: nothing on the ground trades with it profitably, and attacking into it costs two bodies for one. That body alone makes it a first-pickable bomb, the kind of card you take into an open seat and let pull you toward black. The reanimation rider is what lifts it above a fair rate. In a midrange goodstuff environment where the early turns trade resources back and forth, the opponent's graveyard reliably holds a 3-drop worth stealing by the time this connects, and first strike guarantees the trigger fires before any chump can interpose.

BG Food wants it most. The archetype's sacrifice and Food loops stock both graveyards, so a deck already inviting trades feeds the trigger without bending its plan. WB Legendaries values the body just as highly but the rider much less: that shell grinds through its own threat density rather than recycling an opponent's, so it is paying for the 4/4 first striker and treating the reanimation as a tiebreaker.

The Sneak cost reads better than it plays. At it is a five-mana ambush, not a turn-four tempo steal: hold up five, snap on an attacker, and bank the trigger on the crackback. Its real tax is Stomped by the Foot, which every black deck runs and which answers this before the rider resolves. Grounded for Life is worse still, because the creature you reanimate arrives tapped under your control, lined up for exactly that removal the following turn.

The whole card is a dare to read other people's graveyards. The combat-damage trigger steals from the player you hit, returning that creature tapped and attacking back at them, which makes this a ninjas-and-aggression engine that scales with how full the table's bins are. The natural home is Yuriko, the Tiger's Shadow, where the Sneak cost approximates a ninjutsu drop, the first strike protects the connect, and the reanimated body becoming an attacker against its owner doubles as a clock. Marrow-Gnawer and other unblockable-aggression black decks want the trigger too, but Yuriko is the cleanest fit: the deck already wants to be hitting players and already values evasion over board presence.

This is a Bracket 3 card and an awkward one below that. In precon-tier play, opponents' graveyards are too shallow for the trigger to reliably pay off, and the body is just a fair 4/4. It needs a pod with real creature decks across the table to do anything, a Bracket 2-3 expectation rather than a Bracket 1 one. cEDH does not want it either, but not because it is slow: Sneak gives it an evasive arrival window. The problem is that its payoff still hinges on connecting in combat, and cEDH games rarely grant the unmolested attack step this needs. The competitive black slots go to tutors and fast mana.

Within a Yuriko shell it competes for the saboteur slot against Mistblade Shinobi or Skullsnatcher, and it loses on consistency (the trigger needs a worthwhile graveyard) while winning on ceiling (a stolen bomb attacking its owner is a swing nothing else at this cost matches). The political read matters: whoever's bin looks best becomes the target, and the table will haggle over who gets shredded first. Invisible at tables full of low-creature decks, which is the real ceiling on its inclusion.

A four-mana 4/4 with Sneak that wants a reanimator shell built around opposing graveyards, which Modern does not have. The trigger only fires after combat damage, and the bodies it steals come back tapped and attacking the player you already hit, so it is a value rider with no clean way to set up its own payoff. Legal, but it has yet to register in tracked tournament play this season. There is no Modern archetype asking for a black combat-damage reanimator at this rate; the dedicated reanimator decks want their bin, not yours.

Legal since its March 2026 release, but yet to register in any tracked Standard deck this season. The reason is structural rather than incidental: the reanimation trigger reads off the opponent's graveyard, not yours, and Standard does not reliably stock the kind of graveyard that makes a stolen creature worth a turn-four attack. Aggro decks empty their hands face-down or onto the board; the creatures in their bins are small things that already traded. The payoff scales with the value sitting in a control or midrange yard, and against those decks a 4/4 first striker, even one with a Sneak window, has to connect through removal and a stocked board first. The card asks you to build around an effect you do not control the inputs to, which is a hard sell when the format's other four-drops bring guaranteed value on cast.

The body is honest at 4/4 for four with first strike, so it is closer to playable-on-rate than most build-arounds. But Standard already has clean threats in that slot, and Sneak's discount does not buy enough when the rider is conditional on the table you are sitting across from.

It rotates with its parent block in the fall 2027 cycle, exact date pending Wizards' announcement, so the timeline is long. Nothing on the announced schedule pushes the graveyard-rich, slow Standard this card wants; if a grindier control metagame develops in a later set, the conversation reopens, but the current and announced pool does not give it a home.

Legal since its printing this season, and so far it has not registered in tracked Pioneer play. The structural reasons are easy to read off the card. Reanimation that pulls from the opponent's graveyard, not your own, is a strange ask in a format where the graveyard decks already have better engines. Izzet Phoenix wants its own bin, not yours. Mardu Greasefang wants Greasefang and a Parhelion II, not a 4/4 that animates whatever the opponent happened to discard. Mono-Black Waste Not is built around your own resources, too. The card's payoff is gated behind both connecting in combat and the opponent having stocked their yard with something worth stealing, which is a lot of conditions to line up for a four-mana threat in a format that runs as much removal as Pioneer does.

Sneak gives it a turn-four arrival window that dodges a sweeper, and first strike means the combat trigger resolves before a chump can trade. Those are real, but they serve a body that has no archetype asking for it. Pioneer has no Sneak-Attack-style cheat shell and no opponent-graveyard reanimator deck; the format's reanimation is self-targeted by design. There is no slot conversation to have here because there is no list it competes for a slot in.

If a graveyard-rich, removal-light metagame ever made stealing the opponent's bin a real plan, the calculus could change. That metagame is not the one Pioneer has. The card needs a deck the format does not currently run.

A 4-mana 4/4 whose payoff is gated behind connecting in combat and behind the contents of an opponent's graveyard. Vintage is a turn-zero format where Black Lotus and the Moxen power out threats and answers before a sorcery-speed creature ever attacks, and the reanimation rider does nothing the turn it lands. Even with Sneak, this is a fair body asking the format to wait for a combat step it rarely reaches. Legal, but yet to register in tracked tournament play.

Reanimation that depends on the opponent's graveyard rather than your own is the wrong axis for Legacy. Reanimator at one mana puts Griselbrand or Atraxa under your control on turn one; this is a 4-mana 4/4 that needs to land combat damage before it raids a bin you do not control, and it pulls the creature back tapped and attacking that player, not at your direction. The Sneak cost is still , paying the Force of Will tax in full, and the body invites Daze and Wasteland on the way to casting it. Legal, but yet to register in tracked tournament play. Does not clear the bar.
