Regeneration

What does it do exactly? I know it prevents a creature from being destroyed but what does it do exactly?

614.8.: Regeneration is a destruction-replacement effect. The word "instead" doesn't appear on the card but is implicit in the definition of regeneration. "Regenerate [permanent]" means "The next time [permanent] would be destroyed this turn, instead remove all damage marked on it and tap it. If it's an attacking or blocking creature, remove it from combat." Abilities that trigger from damage being dealt still trigger even if the permanent regenerates. See rule 701.12.

The become tapped, removed from combat, and all damage is removed from them if they would be destroyed/after lethal damage.

Ok cool so say I swing with a Gladecover scout with {Etgereal Armor} on it and they block with a 3/3 my Gladecover would die but I play {Mending Touch} does my armor stay on GS?

[griffin131]

Yes because it never leaves the battlefield.

[Mattao19]

Awesome thanks man! +1!

{Vulpine Goliath}?
Yes - it's removed from combat but you had to do the 3 damage to make that happen so...

I my {volpine Goliath} attacks and is blocked by his {death bellow raiser} and he regents it, 3 damage goes through even though his creature is removed from combat yes?

Regeneration is a replacement effect for being destroyed. Instead of moving to the GY, the creature is tapped, removed from combat and all damage assigned to it is removed. In this particular case, his death bellow raiser is destroyed because he took lethal damage during combat. After damage is assigned, he has taken lethal damage. Normally this would move him to the GY, but instead regeneration kicks in. He becomes tapped if he wasn't, he is removed from combat and is no longer considered a blocking creature (but your fox is a still a blocked creature), and all damage is removed from him.

I hope this makes it a little clearer.

[Pleeb]

Correct. All damage is applied simultaneously.

All assuming {Deathbellow Raider} hadn't stayed tapped after having to attack the turn prior ;)

If the raider is assigned as a blocker in the original phrasing of the question, I'm going to assume that it was assigned legally. There are several situations that will leave the raider untapped and able to block including summoning sickness.

All assuming
