Mycologist 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

At the beginning of your upkeep, put a spore counter on this creature. Remove three spore counters from this creature: Create a 1/1 green Saproling creature token. Sacrifice a Saproling: You gain 2 life.

Complete guide

Mycologist is a versatile Human Druid that specializes in the slow but rewarding cultivation of fungal life. This two-mana white creature provides a consistent engine for generating tokens and sustaining your life total throughout a long match.

A Natural Cycle of Growth

Mycologist operates on three distinct abilities that work in harmony. First, it automatically gains a spore counter at the start of your upkeep. Once you have accumulated three counters, you can remove them at any time to create a 1/1 green Saproling token. Finally, you can sacrifice any Saproling you control—not just those created by Mycologist—to gain 2 life.

Timing and Resolution

The first ability is a triggered ability that goes on the stack at the start of your upkeep; you don't need to pay mana for this to happen. The second and third abilities are activated abilities. Because they do not have the tap symbol, you can use them the same turn Mycologist enters the battlefield, provided you have the necessary counters or Saprolings to pay the costs.

Strategic Considerations

A common mistake is forgetting that the sacrifice ability is a free action that can be used at instant speed. This makes Mycologist an excellent defense against removal spells or as a way to gain life in response to lethal damage. Remember that removing counters is the cost to create a token, so your opponent cannot destroy Mycologist in response to prevent the token from being created once you have announced the ability.

When to Deploy

Play Mycologist early in the game to start ticking up counters immediately. In a stalemate, it acts as an inevitable win condition by building an army or a life buffer. It is particularly effective in decks that can multiply counters or benefit from creatures entering the battlefield.

Interaction examples

Survival Tactics

Saproling

If your opponent attacks you for lethal damage, you can sacrifice a Saproling to Mycologist's third ability. This happens at instant speed, increasing your life total by 2 and potentially keeping you in the game before the combat damage step occurs.

The Long Game

Ornithopter of Paradise

Use Ornithopter of Paradise to produce the mana needed to cast Mycologist on turn two. While Ornithopter of Paradise provides the acceleration, Mycologist provides the late-game utility by turning every three upkeep steps into a new creature for your board.

Defensive Synergies

Esper Sentinel

With both creatures on the board, you create a difficult environment for your opponent. While Esper Sentinel taxes their noncreature spells, Mycologist ensures that even if the opponent finds a way to attack through your defenses, you can sacrifice Saprolings to offset the damage dealt.
