Investigator's JournalHow it works & interactions with other cards

A Wealth of Evidence

When Investigator's Journal enters the battlefield, it checks the number of creatures controlled by each player. It gains a number of suspect counters equal to the highest count found among all players, including yourself. Once on the field, you can spend two mana, tap it, and remove a counter to draw a card. If the journal has served its purpose or you are out of counters, you can also sacrifice it using its Clue ability to draw one last card.

Resolving the Entry Effect

The first ability is a replacement effect that happens as the Journal enters the battlefield. You do not choose a specific opponent; the game simply looks at the board state and identifies the player with the most creatures. For example, if you have two creatures, Opponent A has zero, and Opponent B has five, the Journal enters with five suspect counters. Because this happens as it enters, players cannot respond to the choice of how many counters it gets once the spell begins to resolve.

Timing and Strategy

Common mistakes involve forgetting that the Journal is also a Clue. Even if it enters with zero suspect counters (because no one controls any creatures), you can still pay two mana and sacrifice it immediately to draw a card. However, the most efficient use is to wait for a board stall where a player has many creatures, allowing you to draw multiple cards over several turns for a low activation cost.

Interaction examples

Fueling the Investigation

Sol Ring

If you have a Sol Ring on the battlefield, you can use its ability to add two colorless mana, which perfectly covers the cost to activate the Journal's ability. By tapping the Ring and the Journal while removing a suspect counter, you effectively draw a card without spending any colored mana from your lands.

Fixing and Finding

Arcane Signet

In a Commander game, you might use Arcane Signet to produce the mana needed to cast Investigator's Journal early. If an opponent later builds a large army of tokens, the Journal will enter with many counters, and you can use the mana from the Signet to help pay for the repeated card draw activations every turn.
