The Serpent Society is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.

Official card text

Deathtouch Ward—Get five poison counters. (A player with ten or more poison counters loses the game.) Whenever another creature you control with deathtouch dies, each opponent sacrifices a nontoken creature of their choice.

Complete guide

The Serpent Society is a lethal legendary creature that punishes opponents both for targeting it and for killing your other venomous allies. With a unique Ward cost involving poison counters, it forces your rivals into a dangerous predicament. This Human Snake Villain ensures that every trade in combat turns into a devastating loss for your opponents.

Venomous Defense and Ward

The Serpent Society possesses Deathtouch, meaning any amount of damage it deals to a creature is enough to destroy it. More uniquely, it features a Ward cost of five poison counters. When an opponent targets The Serpent Society with a spell or ability, that spell or ability is countered unless the opponent chooses to receive five poison counters. Since ten poison counters result in losing the game, this Ward cost is exceptionally high and can only be paid twice at most by a single player.

Step-by-Step Resolution

When another creature you control with deathtouch dies, The Serpent Society's triggered ability goes on the stack. First, the game checks if the creature had deathtouch at the moment it left the battlefield. Second, the ability is put on the stack in turn order. Finally, as the ability resolves, each opponent must choose one nontoken creature they control to sacrifice. This choice is made by the opponent, not by you, and it bypasses Hexproof and Indestructible since it does not target.

Timing and Strategy

You should play The Serpent Society when you have an established board of creatures with deathtouch to maximize its triggered ability. It serves as a powerful deterrent against board wipes or targeted removal. Because the sacrifice trigger specified 'nontoken' creatures, it is most effective against decks that rely on a few powerful individual creatures rather than wide token strategies.

Common Mistakes

A frequent error is forgetting that the sacrifice trigger only applies to nontoken creatures; if an opponent only controls tokens, they will not sacrifice anything. Additionally, remember that the Ward ability triggers only when The Serpent Society is targeted; it does not protect against spells that do not target, such as 'destroy all creatures' effects, though the opponent will still lose their nontoken creatures if your other deathtouchers die in the process.

Interaction examples

Sacrificing for Value

Sakura-Tribe Elder

If you control The Serpent Society and Sakura-Tribe Elder, you can sacrifice the Elder to search for a land. However, since Sakura-Tribe Elder does not have deathtouch, The Serpent Society's ability will not trigger. Only creatures with the deathtouch keyword will force opponents to sacrifice creatures upon their death.

Combat Trades

Solemn Simulacrum

If an opponent attacks you with Solemn Simulacrum and you block with a creature that has deathtouch while The Serpent Society is on the battlefield, both creatures die. The Serpent Society sees your deathtouch creature die and triggers, forcing your opponent to sacrifice a nontoken creature (which could be another creature they control, as the Simulacrum is already in the graveyard).
