TLDR
- MTG Radiation uses rad counters placed on players, not permanents.
- At the start of your precombat main phase, rad counters make you mill that many cards.
- For each nonland you mill this way, you lose 1 life and remove 1 rad counter.
- Lands are the awkward part: they get milled, but they do not remove rad counters.
You know that warm, cozy feeling of shuffling up Commander and thinking, “Nothing bad can happen before I even cast a spell”? MTG Radiation exists to fix that. It is a Fallout-flavored mechanic that turns your own library into a slow-motion liability and politely asks if you would like to mill, take damage, and maybe enable your graveyard deck all at once.
How MTG Radiation Works
Radiation shows up as rad counters, which are counters players get. They stick around until something tells you to remove them. They do not wear off at end step like a reasonable debuff.
Here’s the core loop:
- Beginning of your precombat main phase: If you have rad counters, you mill a number of cards equal to your rad counters.
- Then you check what you milled:
- For each nonland card milled this way, you lose 1 life and remove 1 rad counter.
- Lands get milled too, but they do not reduce your radiation level.
This is why rad counters feel “self-cleaning,” but only if your deck keeps cooperating and flipping nonlands. If you hit lands, the rads hang around like a houseguest who “just needs one more night.”
A Quick Example (Because Numbers Calm People Down)
You have 5 rad counters.
- You mill 5 cards.
- Let’s say you mill 3 nonlands and 2 lands.
- Result: you lose 3 life and remove 3 rad counters, leaving you with 2 rad counters for next turn.
Next precombat main phase, you mill 2. And so on, until you either stabilize… or your deck keeps serving you lands like it is trying to be funny.
How to Play With (or Against) Radiation
Think of rad counters as a clock with mood swings:
- If you’re giving rads: you want to stack counters fast and punish the table for trying to ignore them. Proliferate is especially rude here because it can add counters to players who already have them.
- If you’re taking rads: treat your life total like it is a resource you would like to keep. Also, remember the upside: you are filling your graveyard, which means recursion and reanimation decks sometimes pretend Radiation is “value” (they are lying, but it is useful).
FAQs
Do rad counters go away on their own?
Only partially. You remove rad counters when you mill nonlands from the rad trigger, or when another effect explicitly removes them.
Can I die to Radiation before I do anything?
Yes. The rad trigger happens at the beginning of your precombat main phase, so you can absolutely get irradiated into the floor before casting a spell.
Do I lose instantly if I mill my whole library?
Not from milling itself. Milling empties your library, but you usually lose when you later have to draw from an empty library.
