Herd Baloth 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

Whenever one or more +1/+1 counters are put on this creature, you may create a 4/4 green Beast creature token.

Complete guide

Herd Baloth is a powerhouse in any deck focused on +1/+1 counters, turning small growth into a massive army. This five-mana Beast punishes opponents by flooding the board with 4/4 tokens whenever it receives a permanent boost. Understanding the timing of these triggers is key to maximizing your board presence.

One or More Counters

The ability of Herd Baloth triggers whenever one or more +1/+1 counters are placed on it. Note that the number of tokens created is always one 4/4 green Beast creature token per trigger, regardless of whether you placed one counter or ten counters at the same time. However, if counters are placed in separate instances or events, the ability will trigger for each of those events.

The Trigger Resolution

When a +1/+1 counter is placed on Herd Baloth, the ability goes on the stack. Because it says 'you may,' you choose whether to create the token as the ability resolves. If Herd Baloth leaves the battlefield before the ability resolves, you can still create the 4/4 token because the game uses last known information to confirm that counters were indeed placed on it.

Timing and Strategy

Since the ability triggers on any effect that places a +1/+1 counter, it works with spells, activated abilities, and even other triggered abilities. To get the most value, look for effects that place counters repeatedly rather than all at once. Because the tokens created are 4/4, they often outsize the blockers your opponent might have, allowing you to quickly take over the game.

Interaction examples

Doubling the Herd

Roaming Throne

If you have Roaming Throne on the battlefield with 'Beast' chosen as the creature type, Herd Baloth's ability will trigger an additional time. When a +1/+1 counter is placed on Herd Baloth, you will get two separate triggers, allowing you to create two 4/4 green Beast creature tokens instead of just one.

Generic Support

Solemn Simulacrum

While Solemn Simulacrum helps you reach the five mana required to cast Herd Baloth by searching for a basic land, it does not directly interact with the Baloth's triggered ability. You will need a third card or effect that specifically places a +1/+1 counter on Herd Baloth to begin generating the 4/4 Beast creature tokens.

Token Synergy

Beast

When Herd Baloth receives a +1/+1 counter, you create a token named Beast. This token is a 4/4 green creature. It does not have any abilities of its own, but its high power and toughness make it a significant threat that can be used for attacking or blocking immediately after the turn it was created (assuming it doesn't have summoning sickness).
