How a rad counter resolves
Rad counters arrived with the Fallout Commander decks and they behave unlike any other counter in the game, because the effect is a three step sequence rather than a single number.
At the beginning of your precombat main phase, if you have one or more rad counters:
- Mill a number of cards equal to the number of rad counters you have.
- For each nonland card milled this way, you lose one life.
- Remove that many rad counters from yourself.
Read step three carefully. You remove a number of counters equal to the number of nonland cards milled, not the total milled. Lands do not pay for their own removal.
The land math nobody mentions
This is the single most useful thing to understand about the mechanic, and it explains why rad counters underperform expectations at every table.
Take a normal Commander deck at 38 lands out of 99. That is roughly 38% lands. Now give yourself five rad counters:
- You mill five cards
- On average, about two are lands and three are nonlands
- You lose about three life, not five
- You remove about three counters, so two remain
So a five rad counter pile does about three damage and leaves you with two counters going into next turn. The face number overstates the damage by roughly 40%, and it understates the persistence, because the counters decay slower than they look like they should.
For a 60 card constructed deck at 24 lands, the ratio is friendlier to the attacker: 40% lands, so a similar discount applies. Either way, plan on roughly 60% of the printed number in actual life loss.
The decay trap
Because lands do not remove counters, a rad counter pile is stickier than a one-shot effect. Someone who hits you with a large number of rad counters is not doing that damage once. They are setting a bleed that continues, at a shrinking rate, for several turns.
The counterintuitive consequence: the more lands you draw off the top, the longer the rad counters stay. A land-heavy stretch is simultaneously good for your life total and bad for how long you keep milling.
Timing: main phase, not upkeep
Rad counters resolve at the beginning of your precombat main phase. Most players assume upkeep, because that is where most recurring triggers live, and they lose games to the difference.
What this means in practice:
- Anything you want to do about your rad counters must happen in your upkeep or draw step
- You draw for turn before the rad trigger, so the card you drew is safe
- Effects that shuffle your graveyard back in are best used in response to the rad trigger, not before it
If you are at low life and holding a way to gain life or remove counters, that window is narrower than instinct suggests.
When rad counters are actually good
Two situations, and they are almost opposites.
As a decking clock, not a damage clock
Stop thinking about the life loss. Five counters milling five cards a turn, sustained across a long Commander game, is a genuine threat to someone’s library, and it is a threat that is very hard to interact with because there is no permanent to remove. The life loss is a bonus that closes out the last few points.
On yourself, in a graveyard deck
This is the play most people miss. If your deck wants cards in the graveyard, rad counters are a repeatable, free, uncounterable self-mill engine. You are paying life for something you wanted anyway, and the counters partially replenish themselves off milled lands.
Reanimator strategies, delirium style payoffs, and anything that cares about card types in the yard all get real value here. Giving yourself rad counters is a cost only if you had no use for the graveyard.
Rad counters versus poison counters
Both are alternate-axis counters that sit on the player rather than a permanent, so it is worth being clear on how differently they behave.
| Rad counters | Poison counters | |
|---|---|---|
| Threshold to win | None, there is no rad kill | Ten, and the game ends |
| Decay | Yes, they shrink each turn | No, they are permanent |
| Effect per turn | Mill and incidental life loss | Nothing until ten |
| Interaction | Hard, no permanent to remove | Hard, same reason |
| Realistic clock | Slow, grindy | Fast in a dedicated deck |
Poison is a win condition. Rad is an attrition tool. A deck built on rad counters is really a mill deck with a life-loss rider, and it should be evaluated against other mill options rather than against other damage sources.
Common misconceptions
“Rad counters are like poison, get to ten and you lose.” There is no rad threshold. Nothing happens at any particular number.
“They all go away after one trigger.” Only if every card milled was a nonland, which is unlikely.
“I can respond to the mill by removing the counters.” You can, but the trigger has already used the count from when it was put on the stack in most implementations, so read the specific card. Removing the counters after the trigger is on the stack generally does not stop it.
“It happens during my upkeep.” It does not. Precombat main phase.
