In response to your query regarding any preference recover v call of the netherworld in a deck as light in creatures as this ( i agree with mrmoto upping the creature count would help ) anything that gets you back a creature from your graveyard is vital if it draws you a card as well its a bonus
i'd play them both and c how well they work out for you, you also need creatures for scarscale ritual to work ( i play it in my red/black aggro deck with a somewhat higher creature count than this and sometimes i struggle to find targets for it,but its good when played on the last phase of keldon marauders or giant baiting before they leave play
and then recover the marauders for further play
mana permitting
. i agree with your comments about bonesplitter in ext that would make the damage u take to play the sangrophage almost worthwhile ( and the low casting cost is attractive
). i think you should revise how much removal you have and which cards you use for it . As i see it you have the following options :-
1 terror cc 1b +1 destroys any nonblack creature no regeneration
2 nameless inversion cc 1b +1 +3/-3 can destroy black creatures
3 tendrils of corruption cc 1b +3 damage = number of swamps yuo control + you gain life
4 strangling soot cc 1b +2 destroy creature with 3 or less toughness (can be played from graveyard for 1r +5 ( double use but needs red to be splashed )
5 eyeblights ending cc 1b +2 destroy target non elf creature
6 morsel theft cc 2b +2 / 1b+1 with prowl deals 3 damage to target player and you gain 3 life
7 chill to the bone cc 1b +3 destroy target non snow creature.
There may be other (these are just the ones that spring to my mind in standard ( no doubt some of our more knowledgeable clanmates will add to this list
)
As i see it the most efficent ones are terror and nameless inversion ( at least against most decks and in the early game the low casting costs help you ) then if you have creatures with evasion (i'm thinking prickly boggarts fear here) the prowl cost of morsel theft is appealing and life gain is great to. Then we come to the best of the later game plays (you need the swamps to make it ultra effective
) tendrils of corruption big hitting and life gain to ( great against those aurochs baloths etc ) the 2 other cards eyeblights ending and chill to the bone are both useful against the right matchups . So i would play 3 each of terror nameless inversion and tendrils move 3 festercreep to the sb for use against saps storm and elf token decks and put in 3 pricky boggrts and 3 morsel theft and c how that plays
I must say having been on the recieving end dash hope is a very good card for mono black which generally doesn't have any counters to either creatures or spells I would reduce the scarscale ritual by 1 or 2 ( if you have enough targets for it u could up it and reduce ur removal) and put in a couple of chilling shades.
Once again will other clanmates please comment i'm probably screwing up a perfectly viable deck with my suggestions so lets please help out here
I only wish i had the confidence to post my deck list here and leave it open to comment like Timmy has done
Well once again those are my thoughts
