@Kitteh: We all have too little time.
That's why I love my food chain goblin deck so much.
A dozen win possibilities but if everything lines up its a first turn kill if I go second, second turn kill if I go first.
I hope I can recreate something like it in Arena.
In this deck I either win with the combo of food chain, goblin recruiter and goblin ringleader. Bringing about 20ish goblins into play on turn 1 or 2 (or later).
Another win possibility is just playing so much goblins and overwhelm the opponent.
If you get a Zo-zu the punisher real early you make it a hard decision for your opponent to play a land and take 2 damage or play no land.
Siege gang commander with it's tokens and you can launch them for 2 damage.
Krenko, mob boss doubles your goblins every turn.
Plus a bunch of other helpfull goblins and special lands or elvish spirit guide to help with mana.
So either hand you get, will let you do something that might help you win.
