Mr. House, President and CEOHow it works & interactions with other cards

High Stakes Triggering

Mr. House has a triggered ability that watches for any die roll. If you roll a 4 or higher on any die (including 20-sided dice or others), you create a 3/3 Robot. If that roll is a 6 or higher, you get the Robot and a Treasure token. Note that if you roll multiple dice at once, this ability triggers separately for each die that meets the numerical requirement.

Activating the House

Mr. House's activated ability costs four mana and requires him to tap. By default, you roll one six-sided die. However, for every mana spent from a Treasure to pay that four-mana cost, you add another die to the roll. These dice have no effect on their own, but they exist specifically to trigger Mr. House's first ability multiple times in a single turn.

Common Misconceptions

A common mistake is thinking the dice from the activated ability do something else, like dealing damage or buffing creatures; they only exist to trigger 'whenever you roll' effects. Additionally, remember that the 'instead' in the first ability means you don't get two Robots on a 6; you get one Robot and one Treasure. Finally, the Treasure bonus for the activated ability only counts mana from Treasures spent on the {4} cost, not mana from other sources.

Optimal Timing

Because Mr. House requires tapping, he is best used at the end of an opponent's turn. This allows you to untap with your new Robots ready to attack. If you have extra Treasures, always prioritize spending them on his ability to increase the probability of hitting those 4s and 6s.

Interaction examples

The Treasure Engine

Mr. House, President and CEOTreasure

You control Mr. House and four Treasure tokens. You activate Mr. House's ability by sacrificing all four Treasures for mana. Because you spent four mana from Treasures, you roll five six-sided dice (1 base + 4 bonus). If you roll a 1, 3, 4, 6, and 6, the first ability triggers three times. You will create three 3/3 Robots and two Treasures.

Doubling the CEO's Output

Mr. House, President and CEORoaming Throne

With Roaming Throne on the battlefield naming 'Human', Mr. House's triggered ability triggers an additional time whenever you roll a 4 or higher. If you roll a single 6, instead of getting one Robot and one Treasure, you get two Robots and two Treasures.

Resource Management

Mr. House, President and CEOSolemn Simulacrum

You have Solemn Simulacrum and Mr. House. You use mana from three lands and one Treasure to activate Mr. House's ability. You roll two dice. If both are 6s, you generate two Robots and two Treasures, effectively replacing the Treasure you spent and netting a profit in board presence.
