Everyday Interactions & Common Rulings

Damage vs. life loss, counters, tapping, protection, regeneration, and lifelink.

12 min read · Lesson 8 of 8

Damage vs. loss of life

These feel the same (both lower life) but behave differently:

  • Damage comes from a source, can be prevented or redirected, and can trigger "whenever [something] is dealt damage" abilities. Damage to a player causes them to lose that much life.
  • Loss of life (e.g. "you lose 3 life," paying life) is not damage — it can't be prevented by damage-prevention effects and doesn't trigger damage abilities.

Counters that cancel, and tapping

If a permanent has both +1/+1 and −1/−1 counters, they annihilate in pairs as a state-based action until only one kind remains. Counters are not abilities — removing a creature's abilities does not remove its counters.

A creature being tapped only means it's turned sideways (usually from attacking or paying a {T} cost). It does not shut off the creature's static abilities, and tapped creatures still have their power/toughness and keywords.

Protection & regeneration

Protection from [quality] is remembered as DEBT: the permanent can't be Damaged (that damage is prevented), Enchanted/Equipped, Blocked, or Targeted by anything of that quality.

Regeneration ("regenerate this creature") sets up a shield: the next time it would be destroyed this turn, instead it's tapped, removed from combat, and its damage is healed. Regeneration only replaces destruction — it does nothing against sacrifice, exile, or a creature with 0 toughness.

Lifelink and simultaneous effects

Lifelink is not a triggered ability. When a source with lifelink deals damage, its controller gains that much life at the same time as the damage is dealt, as part of the same event. There is no trigger to respond to and it can't be "missed." A single lifelink creature blocking and being blocked still gains life for all the damage it deals.

Lesson test

Answer these 8 ruling questions to complete the lesson. You need 70% to pass — passing marks the lesson done and counts toward unlocking the level exam.

A creature has one +1/+1 counter and one −1/−1 counter placed on it.

Q1. What happens?

An effect would prevent the next 3 damage that would be dealt to you. An opponent's spell instead says "you lose 3 life."

Q2. Does the prevention effect stop the life loss?

Q3. A creature with a static ability ("other creatures you control get +1/+1") becomes tapped when it attacks. Its static ability now:

Q4. A creature with protection from red CANNOT be:

You control a creature you've set up to regenerate this turn. An effect then says "Sacrifice a creature," and you sacrifice it.

Q5. Does the regeneration shield save it?

Q6. Lifelink is best described as:

A player tries to respond to their opponent playing a land for the turn.

Q7. Can they respond before the land is on the battlefield?

A 4/4 lifelink creature is blocked by a 2/2, and both deal their combat damage.

Q8. How much life does the lifelink creature's controller gain?

Answer every question, then submit. Pass at 70%.
