Momentum RumblerHow it works & interactions with other cards

Scaling Combat Prowess

Momentum Rumbler features two distinct triggered abilities that check for specific conditions when it attacks. The first ability checks if the creature lacks first strike; if it does, it receives a permanent first strike counter. The second ability checks if it already possesses first strike to grant it double strike for the duration of the turn.

Step-by-Step Resolution

When you declare Momentum Rumbler as an attacker, both abilities trigger simultaneously. You choose the order in which they are placed on the stack. If the Rumbler has no first strike, the first ability resolves to add a counter. Because the second ability checks its condition ('if it has first strike') both when it triggers and when it attempts to resolve, it will see the new counter and successfully grant double strike if you ordered them correctly.

Common Pitfalls

A common mistake is forgetting that the double strike effect is temporary while the first strike counter is permanent. Additionally, if an opponent removes the first strike counter in response to the attack trigger, the second ability will fail to grant double strike because the condition is no longer met at the moment of resolution.

When to Play It

Momentum Rumbler is best utilized in aggressive decks that can protect it during its initial, weaker attacks. Once it has established its first strike counter, it becomes a massive threat that demands an answer, effectively doubling its damage output every time it swings thereafter.

Interaction examples

Accelerating Momentum

Roaming Throne

If Roaming Throne enters the battlefield naming Dinosaur, Momentum Rumbler's abilities will each trigger an additional time. On its first attack, it will receive two first strike counters and gain double strike twice (which is redundant but effective), immediately reaching its maximum potential in a single combat phase.

Standard Combat Progression

Solemn Simulacrum

If you attack with Momentum Rumbler while your opponent controls Solemn Simulacrum, the Rumbler gains a first strike counter and double strike during the declare attackers step. During the first strike combat damage step, the Rumbler deals damage first, potentially destroying the Solemn Simulacrum before it can deal any return damage to the Dinosaur.
