Swarm Shambler 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
This creature enters with a +1/+1 counter on it. Whenever a creature you control with a +1/+1 counter on it becomes the target of a spell an opponent controls, create a 1/1 green Insect creature token.,
: Put a +1/+1 counter on this creature.
Complete guide
Swarm Shambler is a resilient one-drop that punishes your opponents for trying to pick off your creatures. By turning removal spells into new threats, it ensures your board presence remains strong throughout the game.
A Growing Threat
Swarm Shambler enters the battlefield as a 1/1 with a +1/+1 counter, effectively a 2/2 for a single green mana. Its static ability ensures it is always relevant to its triggered ability from the moment it lands, and its activated ability allows it to grow even larger during your opponent's end step or when you have spare mana.
Triggering the Hive
Whenever a creature you control with a +1/+1 counter becomes the target of an opponent's spell, the Shambler creates a 1/1 Insect token. This trigger happens as soon as the spell is cast and goes on the stack above the opponent's spell. This means you get your Insect even if the original creature is destroyed or if the opponent's spell is countered later.
Common Mistakes
Timing is everything. If an opponent targets your Llanowar Elves while it has no counters, and you respond by giving it a counter, the Shambler will not trigger because the creature wasn't a valid trigger source at the moment it was targeted. Additionally, remember that this ability only cares about spells, not activated or triggered abilities from permanents.
Strategic Implementation
Use Swarm Shambler to protect high-value targets. If your opponent must use a removal spell on your mana dorks or your Shambler itself, you at least walk away with a 1/1 Insect. It creates a 'lose-lose' scenario for control players who rely on targeted interaction.
Interaction examples
You cast Swarm Shambler for one green mana. It enters with a +1/+1 counter. During your opponent's end turn, you pay one generic mana and tap Swarm Shambler to add a second +1/+1 counter, making it a 3/3.
Your opponent casts a destruction spell targeting your Swarm Shambler. Because it has a +1/+1 counter, the Shambler's ability triggers. You create a 1/1 green Insect token before the destruction spell resolves. Even though the Shambler dies, you are left with the token.
If you have used an effect to put a +1/+1 counter on your Birds of Paradise, and your opponent targets those Birds with a spell, Swarm Shambler detects this. You will create one 1/1 green Insect token, regardless of how many counters were on the Birds or how many times the spell targeted them.

- #3· Wizards of the Coast
An ability that triggers when a creature becomes the target of a spell resolves before the spell that caused it to trigger. It resolves even if that spell is countered.
No other card is named in this ruling.
- #4· Wizards of the Coast
If a creature without a +1/+1 counter on it becomes the target of a spell an opponent controls, putting a +1/+1 counter on it after that won’t cause Swarm Shambler’s middle ability to trigger.
