Combos Utilizing Darkest-Hour

I have no idea

play darkest hour and choose back for chameleon sprit and it will be really big especially if there are alot of creatures in play

in each turns, bury all creatures in play, or not?

make um black, can't attack, show protection. and gain that life

only to creatures can attack. both are black. cop protects you from taking damage if you decide not to block

kill the opponent's creatures, put +1/+1 counters on repentant vampire and attack!

darkest hour turns all creatures to black. shambler makes all other black creatures get -1/-1

Ok... if any creatures come into play.. everything else dies... But I'm sure you can think of something :)

Black will be probably the most common color, and you just nuke away with the assassin

put out the blightcutter when you have threshhold and then use dakest hour. the blightcutter gains +1/+1 for each black permanent. i've gotten it up to a +30/+30 without d arkest hour so its worth it
