Currency ConverterHow it works & interactions with other cards

What it Does

Currency Converter has three distinct abilities that work in tandem. First, a triggered ability lets you exile any card you discard from your graveyard. Second, its activated ability allows you to draw and discard for two mana, fueling the exile pile. Finally, you can tap it to return an exiled card to the graveyard to generate a Treasure or a 2/2 Rogue token.

Resolution Step by Step

When you discard a card, the triggered ability goes on the stack. Upon resolution, you choose whether to exile that card from your graveyard. Later, when you activate the final ability, you choose a card already exiled by Currency Converter as a cost. If the chosen card was a land, you create a Treasure token; if it was any other card type, you create a 2/2 black Rogue creature token. The card then returns to its owner's graveyard.

Common Mistakes

A common error is forgetting that Currency Converter must be the effect that exiled the card. You cannot return cards to the graveyard that were exiled by other effects like Rest in Peace. Additionally, if Currency Converter leaves the battlefield and returns, it is considered a new object and cannot access cards exiled by its previous iteration.

When to Play It

This artifact excels in decks that focus on looting, cycling, or madness strategies. Since it only costs one mana to cast, it can be deployed early to start accumulating value. It is particularly effective in the late game when you have excess mana to spend on its draw-and-discard ability, slowly building an army of Rogues or a stockpile of Treasure for a big turn.

Interaction examples

Generating Mana

TreasureSol Ring

With Sol Ring on the battlefield, you use its two mana to activate Currency Converter's second ability. You draw a card and discard a land. You use the triggered ability to exile that land. On your next turn, you tap Currency Converter to return the land to your graveyard, creating a Treasure token for extra mana.

Building a Defense

Rogue

If you discard a nonland card like a creature or sorcery, you exile it using Currency Converter's trigger. During your opponent's end step, you tap the artifact to put that card back into your graveyard. You then create a 2/2 black Rogue creature token, providing you with a blocker or attacker for your next turn.

Color Fixing

Arcane SignetTreasure

If you are missing a specific color of mana, you can discard a land card to the Currency Converter. By tapping the artifact to produce a Treasure token, you gain a one-time use of any color of mana, complementing the steady mana provided by your Arcane Signet.
