Research ThiefHow it works & interactions with other cards

Tactical Deployment and Evasion

Research Thief possesses two key keywords: Flash and Flying. Flash allows you to cast this spell any time you could cast an instant, potentially surprising an opponent by providing a blocker or an unexpected damage-based draw trigger. Flying provides the evasion necessary to soar over grounded blockers, making it easier to connect with the opponent's life total and activate its triggered ability.

Drawing from Combat Damage

The core ability of Research Thief triggers whenever an artifact creature you control deals combat damage to a player. Note that 'combat damage' is specifically damage dealt during the combat damage step as a result of attacking; it does not include damage from activated or triggered abilities. Since Research Thief is itself an artifact creature, it can trigger its own ability when it successfully attacks a player.

Common Timing Mistakes

A common mistake is forgetting that Research Thief must be on the battlefield at the moment the combat damage is dealt to trigger its ability. If you cast it after damage has already been processed, you will not draw cards for that combat. However, if you cast it during the Declare Blockers step, it will be present for the Combat Damage step, successfully triggering for itself and any other attacking artifact creatures that connect.

Optimizing Your Card Advantage

To maximize the value of Research Thief, you should play it in decks featuring high-power artifact creatures or those with evasion. It effectively turns every unblocked construct or golem into a source of card draw. Because the ability triggers for each artifact creature individually, hitting a player with three artifact creatures results in three separate draw triggers, giving you immense resource recovery.

Interaction examples

Ramping into Research

Solemn Simulacrum

You control Solemn Simulacrum and attack an opponent who has no blockers. Before damage is dealt, you use Flash to cast Research Thief. During the combat damage step, both Solemn Simulacrum and Research Thief deal damage to the player. Research Thief's ability triggers twice, allowing you to draw two cards in addition to the land you previously searched for.

Doubling the Knowledge

Roaming Throne

You have Roaming Throne on the battlefield with 'Moonfolk' or 'Wizard' chosen as the creature type. When Research Thief deals combat damage to a player, its ability triggers. Because Roaming Throne sees a triggered ability of a creature of the chosen type, it causes Research Thief's ability to trigger an additional time, resulting in two cards drawn from a single attacker.

Direct Combat Synergy

If you control Research Thief alone, it acts as a self-contained engine. Due to its Flying keyword, it can often bypass an opponent's ground forces. When it deals combat damage to the player, its own triggered ability sees that an artifact creature (itself) dealt combat damage, allowing you to draw a card immediately.
