With a slower Bidding plan Liliana goes up a bit in value, as does the Brutality
The Pavel deck happily runs some stuff like Omen of Fire that can be completely dead because the deck can usually afford to have dead cards and still be a threat, and the Sunastian deck runs some pretty derpy 'big' creatures, many aren't even cost effective, it just doesn't matter because if you have enough huge creatures it doesn't matter if you paid extra for them, they're still huge creatures that will stomp the opponent into gravy
Crystal Zard for me at least is truly in a league of its own
Roshan, Hidden Magister This four-drop on-curve uncommon legendary 4/4 mono-Black beater is next
Pia Nalaar Pia Nalaar is a reasonable (if not exceptional) card in red artifact/Thopter decks where theres a lot of competition for space
Every creature you cast has the potential to come with an equally threatening buddy, so long as their total power and toughness line up
