Blightsteel Colossus won't work as an animation target either, for the same reason as Emrakul. (unless that's bugged, too)
I haven't played reanimator in a very long time, but either of the Akromas would work well, I'd think. (though with the white one, since it has protection black,
Animate Dead wouldn't work, though
Reanimate will. To contradict myself, I think there's a bug where
Animate Dead will animate protection black creatures. In IRL you can cast it on the dead creature, but then as soon as it comes into play, protection black destroys
Animate Dead and it dies again)
Any of the eldrazi that don't shuffle themselves into your library would definitely be good targets.
Iona, Shield of Emeria is also a wonderful choice.
Looking at the fattie list in manalink right now, those of casting cost 7 or higher, I would recommend Akroma (haste + protection/evasion),
Angel of Despair (permanent destruction), any eldrazi that doesn't shuffle into library,
Godsire (8/8s every turn!),
Iona, Shield of Emeria (control 1 colour of opponent),
Phantom Nishoba (REALLY hard to kill, plus lifegain),
Sphinx of the Steel Wind (lifelink + protections),
Woodfall Primus (permanent control and persist)
