jason -- bsa actually wasn't overpowered but i've traded my copy and am too lazy to find another. i do want to try it again, though. i'll also pick up a messenger and a nemesis. re Skinrender & Nekrataal -- black has enough cipt kill a dude already in shriekmaw and bone shredder and it has enough 4's with damnation and friends. fulmy mage is a favorite of mine and is always in (a bit of LD goes a long way, and the LD deck someone drafted for the first time on weds. was hilarious).
sanctifiers seems meh, is it really worth it to include cards like that and nantuko vigilante indrik stomphowler torch fiend etc. when i already have as much high-power utility removal (vindicate, pulse, decay, putrefy, mortify, qpm, wickerbough, etc.) as i do? also, is call of the herd still good enough?
eric -- i broadly agree with your analysis and am going to pick some nits below.
i think spitting image is one of the few six-drops that has the sheer power and resilience of grave titan. ink-eyes is awful though, i put him in as a way to hilariously hose reanimator but the card is just ... bad.
i like primal command, it seems like a strong card to me even if your above scenario does happen a fair amount. having an incidental graveyard hate mode cements its place in my cube.
ugh, i wonder what happened to my olivia?
i rotate titans in and out. primeval is just kinda bad but i like the other four. sun and inferno and frost are almost always in actually -- grave only sometimes, it's the only titan that can really feel unbeatable ("power concerns") because god is he good against removal and threaten effects. (inferno is more unbeatable if he sticks though, and of course sun can get the most value / be the most mechanically interesting while frost is the king of fatty-on-fatty combat)
last week i added more fatties as the mid-range decks wanted curve-toppers and the reanimator decks wanted, well, cards to reanimate. the problem is finding ones that have that right mix of color, versatility, strength, play. white is the queen of these cards, i can effortlessly list admonition angel, adarkar valkyrie, yosei, sun titan, twilight shepherd as great options to say nothing of evergreen fatties angel of serenity and angel of despair.
i've found red has great options at 5 (maybe too many, which is why nalaar though i love her is out!) but for red fatties 6+ our selection sucks. we get hostility, flayer of the hatebound, ancient hellkite, balefire dragon, bogardan hellkite, charmbreaker devils, greater gargadon, hateflayer, moonveil dragon, wort the raidmother, valleymaker, ryusei the falling star ... kinda lame? the options when you add another color are much better (aurelia, broodmother, borborygmos enraged) but still kinda lacking in quantity. i'm leaning towards always including broodmother and borbor in addition to aurelia, are there any others i failed to mention (preferably mono-red) or unfairly dismissed above?
