Atarka Red:
In:
1 Arc Lightning
1 Kolaghan's Command
2 Scab-Clan Berserker
1 Duress
1 Duress/Boiling Earth
Out:
2 Goblin Heelcutter
1 Treasure Cruise
1 Zurgo
1 Exquisite Firecraft
1 Zurgo if wanting to add in the last Duress or Boiling Earth. He just isn't a good blocker.
GW Megamorph:
In:
4 Self-Inflicted Wound
1 Duress
1 Ob Nixilis Reignited
1 Arc Lightning or Act of Treason are also reasonable if you want. Keep in more removal otherwise
Out:
2 Exquisite Firecraft
1 Zurgo
1 Abbot
1 Goblin Heelcutter
2 Wild Slash
Esper Dragons:
In:
2 Self-Inflicted Wound
2 Duress
1 Ob Nixilis Reignited
1 Rending Volley
2 Scab-Clan Berserker
1 Outpost Siege
1 Kolaghan's Command
Out:
4 Draconic Roar
3 Wild Slash
2 Goblin Heelcutter
1 Exquisite Firecraft
If they bring in Jace or you think they will be sure to leave in Wild Slash for the Self-Inflicted Wounds. I think adding a Despise to the board over the Outpost Siege would be fine as well.

I haven't tested enough to give a solid guide here. This is my general idea but depending on the way the deck is built should dictate how aggro you need to be. Cut the some Draconic Roars if they aren't running Mantis Rider.
