I like creature decks that end with creatures big and stompy (somehow that description should apply to Angels as well). Favorites so far are Saprolings, Angel Stompy, and Reanimate. Exceptions include instant combo kills (e.g. Dragonstorm), as the game supposedly ends once I get to the good part, and infinite creature spam, as that's like an instant combo kill, too. My preference is Legacy Format, which probably consigns them to some low tier, but that's okay.
Reanimate is problematic, though. Running a selection of the "best" creatures seemed to be guaranteed fun, but it's become a waiting game for anything better to come along. Meanwhile other cool creatures don't quite make the cut, and the originals lose their luster. Pulling up an old deck list, I had:
Angel of DespairEmpyrial ArchangelInkwell Leviathan <--
With complementary lighthouse (wait, negative on the last... what a weird bugger)
Iona, Shield of EmeriaSphinx of the Steel Wind <-- Love the flavor text
Has anything taken their place?
