Magnifying Glass

A mana rock that moonlights as a card-advantage engine, except the rates are stacked so the second job never rivals a real one. Three mana for a colorless source is already a tax over the basics it pretends to stand in for, and the Investigate mode demands four more mana plus the tap before a single Clue appears, which then wants two more to cash. Add up the entire chain and you are spending nine mana across several turns to draw one card, with the rock sitting idle on the turns you would rather be drawing. The conservatism is deliberate: a colorless source that gives slow, grindy decks somewhere to dump surplus mana in the late game, engineered so it never becomes efficient enough for an aggressive or combo shell to want. That ceiling was designed in on purpose. This is an artifact for the player already ahead on cards who needs a mana sink for a flooded board, not the player trying to break parity. The Clue mechanic finds far sharper expression on creatures and cheap spells that fold investigation into work you were doing regardless; here the token hangs off a body of mana that has to justify itself first.
