What does Survival of the Fittest actually do?

For a green mana, discard a creature card and search your library for another creature card, putting it into your hand. It has no per-turn limit, so with enough green mana it can dig through most of a deck in a single turn.

Why is Survival of the Fittest good with graveyard strategies?

Every activation puts a creature into the graveyard as a cost, which is exactly what reanimation spells want — Survival finds the best target for a reanimation spell while simultaneously filling the yard with the fuel it needs, doing two jobs at once for one green mana.

Is Survival of the Fittest a combo piece?

It's most famous as a tutor, but it enables real combos too — finding both halves of a creature-based combo in one turn, or discarding a combo piece with an interesting death or graveyard trigger, are both common lines in decks built around it.

Strategies it goes well with

Reanimator. Every activation is a free discard into the graveyard as well as a tutor, feeding a reanimation spell its target for no extra cost.
Creature-based combo decks. Repeatable, uncapped access to any creature in the deck makes assembling a two-creature combo far more consistent than drawing into it naturally.
Toolbox green decks. Finding exactly the right creature answer — a Reclamation Sage for an artifact, a big blocker, a finisher — turns the deck into a series of correct answers rather than a fixed plan.

How it does in Commander

As the commander

It's an enchantment, not a creature, so it's never a commander — it's a build-around engine card that lives entirely in the 99.

In the 99

One of the most efficient repeatable tutors green has ever printed, and the backbone of dedicated reanimator and creature-toolbox decks that can afford to build specifically around it.

Formats it's strong in

Reanimator shells. It fills the graveyard and finds the reanimation target in the same activation, which is close to the ideal effect for that archetype.
Green creature-toolbox decks. Uncapped, repeatable access to any creature turns a big, varied creature base into a series of tutorable answers.

Formats it's weak in

Low-creature-count decks. With few creatures to discard or find, the engine has little to feed on and little to find.
Decks that can't use a discarded creature. Without reanimation or a graveyard payoff, the discard half of the cost is a real loss rather than a resource being redirected.

Synergistic cards

Reanimate — The cheapest reanimation spell, turning Survival's discard into the setup for a huge creature a turn early.
Protean Hulk — A creature that's often better discarded than cast — its own death trigger tutors up a combo, so Survival finding it and then feeding it in is a full turn of value.
Eternal Witness — A creature worth finding on its own, and a fine target to discard and later reanimate for the ETB.
Karmic Guide — Reanimating creatures Survival has discarded, including itself as a loop with the right pieces.

Is it worth the price?

Survival of the Fittest is an older, lower-print-run card that's stayed pricier than most 2-mana enchantments as a result — it's a real investment rather than a budget pickup. Worth it specifically for a dedicated reanimator or toolbox green deck; a poor fit to buy for a list running only a handful of creatures.
