Prosperous PartnershipHow it works & interactions with other cards

What It Does

When Prosperous Partnership enters the battlefield, its triggered ability creates two 1/1 green and white Citizen creature tokens. Beyond this initial value, it features a repeatable activated ability: by tapping three untapped creatures you control, you can create a Treasure token. Note that the activated ability does not use the tap symbol, meaning you can tap creatures that are affected by summoning sickness.

Step-by-Step Resolution

First, cast Prosperous Partnership. When it resolves and enters the battlefield, the triggered ability goes on the stack. Once that resolves, you create two Citizen tokens. From this point forward, at any time you have priority, you can activate the second ability. You choose any three untapped creatures you control—including the newly created Citizens—and tap them as a cost. The ability then goes on the stack and, upon resolution, creates one Treasure token.

Common Mistakes

A common point of confusion is whether the Citizens can be tapped the turn they are created. Because the cost is 'Tap three untapped creatures' and doesn't use the {T} symbol, summoning sickness does not prevent those creatures from being tapped for this ability. Additionally, remember that you cannot 'double dip' by tapping a creature for its own ability and Prosperous Partnership simultaneously; a creature can only be tapped to pay for one cost at a time.

When to Play It

This enchantment is best played in the early to mid-game to maximize the mana acceleration from Treasure tokens. It is particularly effective if you have high-toughness blockers or utility creatures that aren't attacking, allowing you to extract value from them during your opponent's end step.

Interaction examples

Immediate Wealth Generation

After casting Prosperous Partnership, you create two Citizen tokens. If you already controlled at least one other creature, you can immediately tap that creature along with the two new Citizens to create a Treasure token, effectively refunding one mana of any color for your next spell.

Taxing and Ramping

With both enchantments on the field, you have multiple streams of income. While Smothering Tithe punishes your opponents for drawing cards by generating Treasure, Prosperous Partnership allows you to proactively convert your board of Citizen tokens into even more Treasure tokens whenever you don't need them for combat.

Defensive Utility

Prosperous PartnershipGhostly Prison

When your opponent is restricted by Ghostly Prison, they may choose not to attack. On their end step, you can tap your untapped blockers using Prosperous Partnership's ability to create a Treasure token. This allows you to advance your mana state without leaving yourself vulnerable during your own turn.
