The Rubblefield was once among the wealthiest districts in Ravnica. All it took was a single wurm to reduce it to ruins.


Cards like Siege Wurm

Siege Wurm stands tall as a formidable creature in Magic: The Gathering, boasting trample and a notable 5/5 body, making it a threat on the battlefield. It shares traits with other strength-focused green creatures, such as the Craw Wurm, another giant in the green lineup with a significant power and toughness. However, what makes Siege Wurm unique is its convoke ability, allowing you to tap creatures you control to help cast it sooner than its seven mana cost would typically allow.

Comparing Siege Wurm to the likes of Battering Wurm, we notice the beatdown potential inherent in creatures with trample. Battering Wurm, while only a 4/3, presents an interesting upside with its ability to become unblockable when facing a player with no untapped lands. Yet, it lacks the efficiency and potentially reduced cost of Siege Wurm’s convoke mechanic. On the other side of the spectrum is Enormous Baloth. Though it has an impressive 7/7 line, it lacks both trample and an alternate casting option, making it less versatile in a dynamic game.

Analyzing each creature’s characteristics, it’s clear that Siege Wurm offers a blend of power and strategic casting flexibility, securing its position as a valuable card amongst its creature peers in green mana strategies within the realm of Magic: The Gathering.

Card Pros

Card Advantage: Siege Wurm can be a sizable presence on the field, potentially swinging the board state in your favor. Summoning this heavy hitter can deter opponents from attacking, maintaining your life total while pressuring theirs.

Resource Acceleration: With its convoke ability, Siege Wurm allows you to tap your creatures to help cast it, effectively accelerating the use of your resources and possibly getting it on the battlefield much earlier than its seven-mana cost would typically allow.

Instant Speed: While Siege Wurm isn’t an instant itself, its convoke mechanic benefits from spells and abilities you may cast at instant speed to create or buff creatures before tapping them for its convoke cost, allowing for unexpected plays and tactical flexibility.


Card Cons

Discard Requirement: One setback for players considering the inclusion of Siege Wurm in their decks is the reliance on Convoke as a mechanism to cast it more affordably. This could potentially require tapping creatures that could otherwise be used for defense or attacking, somewhat devaluing the immediate board presence of the wurm itself.

Specific Mana Cost: Siege Wurm demands a specific mana combination for its casting cost, which is predominantly green. This can pose a restriction when building a multicolored deck or impact flexibility in mana usage during gameplay, particularly in decks that are less focused on green mana production.

Comparatively High Mana Cost: With a casting cost that includes five mana plus two green, Siege Wurm can be a significant resource investment, especially in the early to mid-game. This can be disadvantageous compared to other creatures with similar power and toughness that may offer additional abilities or come with a lower casting cost.


Reasons to Include Siege Wurm in Your Collection

Versatility: Siege Wurm provides a strong presence on the battlefield that’s suitable for a variety of Green-based decks. As a creature with the trample ability, it can be a game-changer by ensuring damage gets through to opponents, even when blocked.

Combo Potential: Thanks to its Convoke mechanic, Siege Wurm synergizes well with token strategies. You can use your creatures to help cast it earlier than its seven mana cost would normally allow, enabling powerful board states sooner in the game.

Meta-Relevance: While not a staple in every deck type, Siege Wurm holds its own in a meta that favors creature-heavy strategies. As a sizable creature that can be potentially cast for less mana, it can be a cost-effective addition against a range of opponents.


How to beat Siege Wurm

Confronting a Siege Wurm on the battlefield can be a daunting challenge for many MTG players. This creature card is a robust inclusion in green decks, renowned for its trample ability and considerable power. The key to overcoming this formidable opponent lies in strategy and timing. Exploiting the fact that Siege Wurm has a high mana cost and often relies on the convoke mechanic, meaning your adversary might tap their creatures to cast it, can be a game-changer. Timing your removal spells just before it’s cast or while the opponent’s creatures are tapped out can drastically reduce its impact. Board wipes, direct damage spells, or exile effects can efficiently manage the wurm’s presence.

Additionally, employing creature cards with reach or those that can block multiple creatures, like Guardian of the Ages or Hover Barrier, provide a defensive tactic to withstand the Wurm’s trampling blows. By maintaining adequate mana to activate abilities or cast spells during your opponent’s turn, you can maneuver a successful defense or removal and keep the wurm from trampling over your plans for victory.

Ultimately, a strategic approach, leveraging the right cards and precise timing, will ensure that even a creature as formidable as Siege Wurm doesn’t overrun your game. Understanding and predicting your opponent’s moves is crucial to turning the tides and securing a win against this powerful adversary.

Rules and information

The reference guide for Magic: The Gathering Siege Wurm card rulings provides official rulings, any errata issued, as well as a record of all the functional modifications that have occurred.

Date Text
2018-10-05 Because convoke isn’t an alternative cost, it can be used in conjunction with alternative costs.

2018-10-05 If a creature you control has a mana ability with in the cost, activating that ability while casting a spell with convoke will result in the creature being tapped before you pay the spell’s costs. You won’t be able to tap it again for convoke. Similarly, if you sacrifice a creature to activate a mana ability while casting a spell with convoke, that creature won’t be on the battlefield when you pay the spell’s costs, so you won’t be able to tap it for convoke.
2018-10-05 Tapping a multicolored creature using convoke will pay for or one mana of your choice of any of that creature’s colors.
2018-10-05 When calculating a spell’s total cost, include any alternative costs, additional costs, or anything else that increases or reduces the cost to cast the spell. Convoke applies after the total cost is calculated.
2018-10-05 When using convoke to cast a spell with in its mana cost, first choose the value for X. That choice, plus any cost increases or decreases, will determine the spell’s total cost. Then you can tap creatures you control to help pay that cost. For example, if you cast Worldsoul Colossus (a spell with convoke and mana cost ) and choose X to be 3, the total cost is . If you tap two green creatures and two white creatures, you’ll have to pay .
2018-10-05 You can tap an untapped creature you haven’t controlled continuously since the beginning of your most recent turn to convoke a spell.
