Text of card

When Guardians of Koilos enters the battlefield, you may return another target historic permanent you control to its owner's hand. (Artifacts, legendaries, and Sagas are historic.)

Archaeologists depend on automatons inspired by their previous discoveries at Koilos to guard the excavations.


Card Pros

Card Advantage: When casting Guardians of Koilos, the ability to return another target historic permanent you control to your hand can be utilized to re-trigger enter-the-battlefield effects, effectively generating additional value and card advantage without expending extra resources from your hand.

Resource Acceleration: In decks that capitalize on artifact synergies, playing Guardians of Koilos can be part of a strategy that accelerates your mana. It can reset mana rocks or enable repeated uses of other artifacts that can be tapped for resources. This can help you execute key plays faster and more efficiently.

Instant Speed: While Guardians of Koilos itself is not an instant, it can indirectly benefit from instant-speed interactions in MTG. By returning historic permanents with flash or those with instant-speed activated abilities, you can create surprise blockers or use those abilities again, keeping your opponents guessing and maximizing the timing of your strategic plays.


Card Cons

Discard Requirement: Guardians of Koilos lacks any discard effect, meaning it doesn’t directly contribute to strategies that benefit from discarding cards or graveyard interactions, which may not synergize well with decks centered around those mechanics.

Specific Mana Cost: This artifact creature requires a colorless mana pool, which might not be readily available in all types of MTG decks, especially those that rely heavily on colored mana for their other spells and creatures.

Comparatively High Mana Cost: With a casting cost of five mana, Guardians of Koilos may come into play too late in the game where faster, more cost-efficient creatures or artifacts could have had an immediate impact on the board state.


Reasons to Include in Your Collection

Versatility: Guardians of Koilos can adapt to various playstyles, as it finds a place in decks that leverage artifact synergies and require recurring cast effects for strategic advantages.

Combo Potential: This card shines when integrated into engines that capitalize on entering or leaving the battlefield triggers, bridging the gap between intricate combo lines and value plays.

Meta-Relevance: In matchups where resilience to removal is key, Guardians of Koilos can repeatedly protect and recur valuable creatures or artifacts, maintaining board presence against control-heavy opponents.


How to beat

Guardians of Koilos presents a unique challenge on the battlefield. This artifact creature is not just about muscle; its real power lies in its ability to bounce another artifact back to the player’s hand when it enters the battlefield. In essence, it creates a loop for recasting artifacts with enter-the-battlefield effects, potentially building up a significant advantage over time.

To effectively counter this recurring benefit, one strategy is to limit the Guardians’ board time. Efficient removal spells are key. Cards that force an opponent to sacrifice a creature can sidestep the potential to recast the artifact creature. Temporary solutions like Pacifism can render the Guardians harmless, but be aware they do not address the core issue of the looping mechanic.

Disruption is another avenue. Counterspells can prevent the Guardians from entering the battlefield in the first place, breaking the loop before it starts. Hand disruption can rid your opponent of artifacts worth recurring, undermining the value Guardians of Koilos could provide. With these strategies in play, overcoming the resilience of this artifact creature becomes a manageable task.


Cards like Guardians of Koilos

The distinctive recursion ability of Guardians of Koilos sets it apart in the realm of artifact creatures within Magic: The Gathering. Like the Retrievers (Myr Retriever and Junk Diver), Guardians of Koilos returns a fellow artifact to its owner’s hand upon entering the battlefield. However, it diverges in its more substantial form, able to swing in for battle or block adversaries effectively due to its favorable stats.

Another similar entity is the Workshop Assistant, which also promises to salvage artifacts from the graveyard but activates only upon the creature’s death, whereas Guardians of Koilos offers immediate utility upon casting. Additionally, unlike Sculpting Steel or Phyrexian Metamorph which can copy artifacts, Guardians of Koilos maintains its unique role in enabling the player to reuse artifacts with beneficial enter-the-battlefield effects, leading to potential game-shifting consequences.

All factors considered, Guardians of Koilos exemplifies an engine for value, especially when paired with artifacts that have potent abilities upon entering or leaving the battlefield. This positional flexibility across various strategies solidifies its place in MTG as a card that can recur artifacts repeatedly, offering a blend of aggression and tactical advantage.
