Regeneration is a creature ability most common on Green or Black creatures. It prevents a creature from being destroyed by paying the Regenerate mana cost, meaning the creature survives if it was originally going to be destroyed. Any damage dealt to the creature prior to being regenerated is removed. Any damage dealt to the creature after being regenerated remains until end of turn. There are creatures which can regenerate themselves or others and Enchantments which give a creature the Regenerate ability. There are non-Creature non-Enchantment cards which let you regenerate a creature. You need to pay (in most cases) a mana cost to regenerate a creature. Some times, you need to sacrifice a creature, or you may need to pay Life as well. You can regenerate a creature as many times as you want each turn for so long you can pay the cost. You have to pay the Regenerate cost each time it would be Regenerated.

When a creature CAN be regeneratedEdit

• When a card deals damage, you can regenerate the creature that got dealt damage.

Example: If you play Volcanic hammer on Sporeback Troll, he can regenerate himself.

• When a creature attacks and YOU block.

Example: If your opponent attacks with Balduvian Barbarians  and you block with Drudge Skeletons, you can regenerate your blocking creature, in this case the Drudge Skeletons .

• When YOU attack and your opponent blocks.

Example: If Drudge Skeletons gets blocked by Hill Giant.

• With any destroy effect.

When Naturalize is played on an (Artifact) creature, it can be regenerated.

When a creature CAN'T be regeneratedEdit

• When a creature gets 0 Toughness, it is sent to the graveyard as a state-based effect.
• When a creature is returned to the hand of the controller/player/...
• When a creature is already in the graveyard. You can't use regeneration to rise the creatures from death, only to prevent it.
• When a card says it can't be regenerated. (example: Terror)
• When a creature is sacrificed.

Other rulesEdit

Tap/UntapEdit

A creature that has been dealt lethal damage and been regenerated gets tapped afterwards. However, creatures who are already tapped still can be regenerated, but remain tapped.

Attacking after RegenerationEdit

When you regenerate a creature, you can attack in the same turn it was regenerated (and doesn't have Summoning Sickness or any other effect which says so) but only if you can get it untapped.

Getting BlockedEdit

When a creature (which can be regenerated somehow) gets blocked by more than one creature and each has both the same power and toughness of the creature with Regenerate, you only need to pay the cost once. All damage hits the creature at the same time, so one time will suffice.

Deathtouch and RegenerationEdit

You can regenerate from Deathtouch by paying the regeneration cost.

If a creature blocking or blocked by a creature with Deathtouch is dealt enough combat damage to destroy it, its controller does not have to pay regeneration costs twice to keep it alive. One regeneration effect is enough to prevent both lethal damage and Deathtouch.

Trample and RegenerationEdit

When a creature with Trample attacks and is blocked by a creature which can be regenerated, the creature can be regenerated, but regenerate does not prevent any damage done to that creature's controller from Trample.

What the rulebook saysEdit

To prevent a permanent from being destroyed later in the turn. A regeneration effect works like a shield. A spell or ability that says “Regenerate [a permanent]” puts a regeneration shield on that permanent that can be used up at any time during the turn. If a permanent would be destroyed and it has a regeneration shield, it’s not destroyed. Instead, it becomes tapped, it’s removed from combat (if it’s an attacking or blocking creature), and all damage is removed from it. That regeneration shield is then used up. The permanent never leaves the battlefield, so any Auras, Equipment, or counters that were on it remain there. Any unused regeneration shields go away during the cleanup step. Although a permanent with a regeneration shield can’t be destroyed, it can still be put into the graveyard for other reasons.
