Deep Forest Hermit 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

Vanishing 3 (This creature enters with three time counters on it. At the beginning of your upkeep, remove a time counter from it. When the last is removed, sacrifice it.) When this creature enters, create four 1/1 green Squirrel creature tokens. Squirrels you control get +1/+1.

Complete guide

Deep Forest Hermit is a powerful tribal enforcer that brings an entire army of Squirrels with it to the battlefield. While its stay is temporary due to the Vanishing keyword, the impact it leaves on the board can quickly overwhelm your opponents. Let's explore how to maximize this Elf Druid's potential and manage its time on the field.

A Burst of Squirrel Energy

When Deep Forest Hermit enters the battlefield, its triggered ability creates four 1/1 green Squirrel creature tokens. Furthermore, it provides a static +1/+1 bonus to all Squirrels you control. This means that as long as the Hermit is on the battlefield, those four tokens are effectively 2/2 creatures, providing a total of 8 power for just five mana.

Understanding Vanishing 3

The Vanishing mechanic involves three distinct steps. First, the creature enters with three time counters. Second, at the beginning of your upkeep, you must remove one time counter. Finally, when the last time counter is removed, a second ability triggers that forces you to sacrifice the creature. This means the Hermit will naturally leave the battlefield at the start of your third upkeep after it was played.

Timing and Strategy

Deep Forest Hermit is best utilized in aggressive decks that can win before the Vanishing sacrifice occurs, or in decks that can 'blink' the creature to reset its counters and create even more tokens. Remember that the +1/+1 bonus is static; as soon as the Hermit leaves the battlefield (whether through Vanishing or being destroyed), your Squirrel tokens will immediately lose the buff and return to being 1/1 creatures.

Interaction examples

Doubling the Horde

Roaming Throne

If you control Roaming Throne and chose 'Elf' or 'Druid' as it entered, Deep Forest Hermit's enter-the-battlefield ability triggers an additional time. You will create eight 1/1 Squirrel tokens instead of four. Note that Roaming Throne will also cause the Vanishing upkeep trigger to fire twice, meaning the Hermit will lose time counters twice as fast!

Managing the Mana Base

Solemn Simulacrum

In a mid-range strategy, you might use Solemn Simulacrum to accelerate your mana to reach the five mana required for Deep Forest Hermit. Once the Hermit arrives and creates its Squirrel tokens, the Simulacrum serves as a sturdy blocker while your buffed Squirrels focus on attacking the opponent.

The Strength of the Pack

Squirrel

When Deep Forest Hermit enters, it creates four Squirrel tokens. Because of the Hermit's third ability, each of these tokens immediately becomes a 2/2 creature. If you already had other Squirrel tokens on the battlefield from previous turns, they all receive the +1/+1 bonus as well, creating a massive board presence instantly.
