[Kaalia with haste]

More hordeling outburst. Less ankleshankers

More hordeling outburst. Less ankleshankers

Agreed. And maybe one or two  {Hero's Downfall}

[LinkCelestrial]

{Hammer of Purphoros}? Your highest costing spell is {Murderous Cut} followed by {Butcher of the Horde}, so land sacing may be relevant. Plus all haste all the time is good. Otherwise I'd like to see some {Wild Slash}.
