For the top-tier 1 decks, Aggro is king right now. The faster the better;
Mardu Vehicles, Mono-red Eldrazi Aggro, etc.
Although there's been some good control stuff around.
If you're looking for more Janky stuff;
Mono-red burn is do-able
Turbofog is really good against the top tier meta right now, but weak to just about everything else
There's some really cool mill designs around right now, mostly blue, some splash red for killin stuff
Scarab god designs are around too, something to look out for
