Kilo, Apogee Mind — ruling 1

If Kilo is tapped to station a permanent, its last ability will resolve before the station ability resolves.

Kilo, Apogee Mind — ruling 2

When you proliferate, you can choose any permanent that has a counter, including ones controlled by opponents. You can choose any player who has a counter, including opponents. You can’t choose cards in any zone other than the battlefield, even if they have counters on them.

Kilo, Apogee Mind — ruling 3

You don’t have to choose every permanent or player that has a counter—only the ones you want to add counters to. Since “any number” includes zero, you don’t have to choose any permanents at all, and you don’t have to choose any players at all.

Kilo, Apogee Mind — ruling 4

If a permanent or player has more than one kind of counter on them, and you choose for that permanent or player to get additional counters, that permanent or player must get one of each kind of counter they already have. You can’t have them get just one kind of counter they already have and not the others.

Kilo, Apogee Mind — ruling 5

Players can respond to a spell or ability whose effect includes proliferating. Once that spell or ability starts to resolve, however, and its controller chooses which permanents and players will get new counters, it’s too late for anyone to respond.

Kilo, Apogee Mind : règles, fonctionnement et interactions (MTG)

Kilo, Apogee Mind is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.

Official card text

Haste Whenever Kilo becomes tapped, proliferate. (Choose any number of permanents and/or players, then give each another counter of each kind already there.)

Complete guide

Kilo, Apogee Mind is a high-speed engine designed to amplify the power of your board state every time it acts. By combining the immediate impact of Haste with the scaling power of Proliferate, Kilo ensures that every tap counts toward your eventual victory.

Efficiency Through Action

Kilo, Apogee Mind features a triggered ability that occurs whenever the creature becomes tapped. This isn't limited to attacking; any effect that causes Kilo to transition from an untapped state to a tapped state—such as being used for a 'Station' ability or a cost for another spell—will trigger the Proliferate effect. Because Kilo has Haste, you can begin this chain of counters the very turn it enters the battlefield.

Understanding Proliferate

When the ability resolves, you choose any number of players or permanents on the battlefield that already have at least one counter. For each one chosen, you add another counter of every type already present on that object or player. You cannot add counters to cards in other zones, like your hand or graveyard. Once the resolution begins and you choose your targets, opponents cannot respond to stop the addition of counters.

Strategic Choices

A common mistake is assuming you must add all types of counters present on a permanent. If a creature has both a +1/+1 counter and a Stun counter, you must add one of each if you choose to proliferate that creature; you cannot pick and choose among the types. However, you can choose to skip any permanent or player entirely if adding counters to them would be disadvantageous.

Interaction examples

Double the Progress

Roaming Throne

If you have Roaming Throne on the battlefield and chose 'Robot' or 'Artificer' as it entered, Kilo's ability will trigger an additional time. When Kilo attacks or becomes tapped, two separate Proliferate instances are put on the stack. You resolve the first, adding counters to your permanents, and then resolve the second, adding even more.

Immediate Board Scaling

Solemn Simulacrum

While Solemn Simulacrum helps you fix your mana, Kilo can benefit from it if you have other ways to tap Kilo. If you use an effect to tap Kilo while you have a +1/+1 counter on Solemn Simulacrum, the Proliferate ability will trigger. You choose the Simulacrum, adding a second counter to it, making your Golem a more formidable blocker before it eventually dies to draw you a card.
