See how you do. You can aggro on control people and control on aggro people. And still be hitting things with a big axe each turn.

Upgrading Death's Bite and going face wins games very often. Don't use upgrades on the same turn. Space them out to surprise them with an extra weapon swing again and again.

Don't waste warsong commander. Dropping a Berserker on a turn Death's Bite runs out is a surprising amount of damage. Even I am surprised. Haunted creeper can deal 3 damage by suiciding into bigger creatures. Useful for killing taunts at times or getting that 1 damage for execute and giving you an instant 2 damage to use elsewhere.

Upgrading warsong axe is good if you know they don't run taunts. Arcanite Reaper is whatever

Death rattles are just there to be a distraction and make undertakers big. It's too effective not to use and I gave in and am putting them in a lot of decks to great success.

Basically this is about mana. You get a big weapon and you get some creatures that aren't threats now but wil lbe threats once they  build up (warsong, frothing, undertaker.) Either they spend their mana clearing or spend it putting a big taunt. Unless they run ooze or harrison you can pretty much run away with most games. Dream turns are playing greenskin on a weapon that only had one charge left. Surprising your opponent with an extra 5-6 damage over two turns and putting a big body for them to deal with. 

Cleave and Dread Corsair are optional. Dread Corsair is nice because an upgraded warsong axe makes it free. Really good with Warsong Commander too. I want to try other cards in these spots mostly because Cleave feels underwhelming a lot of the time. Cards I'm considering are: Loatheb, Brawl, Gorehowl, Heroic Strike
