Korlash, Heir to Blackblade

Ob, Nixilis the Fallen with Korlash, Temporal Extortions, and Corrupts. Works great.

Korlash yummy! Yes... Run with Lord of the Dead and even Unholy Grotto. The thing I like best about his Granduer abiliy is it specifies Swamp, not basic Swamp. So I just fetch for Leechridden Swamps and/or Dual/Shock lands. Put him back into my hand with Lord of the Undead, or back to the top of my Library if people are picking on my Lord with the Unholy Grotto, and repeat the Granduer process. If I don't or can't overrun my opponent with massive zombies I can just do a nasty Corrupt kill.

Great Art, Great Abilities... Who cares if he can't fly, so long as he stays alive with Regenerate you will be provided with Uber deck thinning and land excel!

I love Korlash, a mono-black just isn't the same without him. Infernal tutor is cool with him :P

This card got insanely powerful after death baron was released. A deathtouching regenerater in a monoblack is the best chump blocker you could ask for. Would be better with flying, but still great the way it is.

Lord of undead...Him 2 Korlash(1 in play) and abuse his grandeur ability.That simple...

Better than Nightmare and I'll tell you why. It's a Zombie. Play this in conjunction with something like Undead Warchief and Call to the Grave, all of a sudden not only does it get an additional +2/+1 but while all your opponents creatures are taking hits, you're Korlash remains untouched free to eat their soul.

You are forgeting urborg...with that land u don't need to play with monoblack, in fact, the decks with korlash are usually b/u with teferi and stuff...Anyway this is a great card, one of the best black creatures and will definetly leave its mark in mtg along with its pricepal, the tarmogoyf

Looks like Nightmare has returned. Should be one of the best black cards in the set.

Don't bother trying to abuse his Grandeur, or build around it. Just picture him as a low costed regenerating Nightmare, with a perk. Solid beater, but lack of evasion can be a pain.

He's 2 mana cheaper than the Nightmare, but he also does not have flying. So at first he will be a smallish regenerating creature at best.

Use Demonic Collusion or similar to grab one more Korlash from your library so you can start making use of the Grandeur ability. Then all you need to do is to grab your discarded Korlash from your graveyard back into your hand, then keep playing the Grandeur ability over and over.

That will probably work alright. But he's still not a flyer and he does not have trample. So he would be easy to block no matter how big he would get. Besides, he can only get so big unless you are playing monoblack in which case your library would contain more swamps up for grabs.
