Arahbo, Roar of the WorldHow it works & interactions with other cards

The Power of Eminence

Arahbo features two distinct triggered abilities. The first is Eminence, which triggers at the beginning of combat on your turn if Arahbo is in the command zone or on the battlefield. This allows you to give another target Cat you control +3/+3 until end of turn for free. The second ability is a combat trigger: whenever another Cat you control attacks, you may pay {1}{G}{W}. If you do, that Cat gains trample and gets a bonus to its power and toughness equal to its current power.

Resolving the Triggers

During your combat phase, the Eminence ability triggers first. You choose a target Cat, and it receives the +3/+3 bonus. Once you declare attackers, the second ability triggers for each attacking Cat. You resolve these one by one. For each trigger, you decide whether to pay {1}{G}{W}. If you pay, the game checks the Cat's power at that exact moment to determine the value of X. This is highly effective because the +3/+3 from Eminence is already applied, making the doubling effect even more potent.

Strategic Timing and Limits

A common mistake is assuming you can pay the {1}{G}{W} multiple times for a single Cat to stack the effect; however, you can only pay once per trigger. Additionally, the Eminence ability requires Arahbo to stay in the same zone from the moment it triggers until it resolves. If Arahbo is on the battlefield when the ability triggers but is moved to the command zone before it resolves, the ability will fail to do anything because he is considered a new object.

When to Unleash the Roar

Arahbo is best played in aggressive decks where you can consistently attack with at least one Cat. Since the Eminence ability doesn't require Arahbo to be cast, you can spend your early mana developing your board with cheaper Cats and save your mana to activate his second ability. Use this to push through lethal damage by giving your largest unblocked (or blocked) Cat trample and a massive power spike.

Interaction examples

Doubling the Roar

Roaming Throne

If you have Roaming Throne on the battlefield with 'Cat' chosen as the creature type, Arahbo's abilities will trigger an additional time. At the start of combat, Eminence triggers twice, allowing you to give two Cats +3/+3 (or the same Cat +3/+3 twice). When a Cat attacks, Arahbo's second ability triggers twice; if you have the mana, you can pay for both triggers to exponentially increase that Cat's power.

Combat Sequence with Arahbo

If Arahbo is in your command zone and you control a 2/2 Cat, the beginning of combat trigger gives that Cat +3/+3, making it a 5/5. When that Cat attacks, you pay {1}{G}{W}. The ability checks the Cat's power (5) and gives it +5/+5 and trample. The Cat is now a 10/10 creature until the end of the turn.

Non-Synergy Example

Solemn Simulacrum

If you attack with Solemn Simulacrum while Arahbo is on the field, no abilities will trigger. Arahbo specifically requires the target or the attacking creature to be a 'Cat'. Since Solemn Simulacrum is a Golem, it does not receive the +3/+3 bonus nor the option to pay for the power doubling and trample.
