we see there's still one role unfilled regardless of its success.
So putting a bunch of 2/2s on the board hasn't given you board control? Are you sure you're milling right? ;) jk but you do have 2 minions so you should have a decent board in terms of having a large amount of coldlights on the board (not that they're necessarily impressive).
1. Card draw / Card Advantage engine 2. Something to kill opposing minions with 3. Your win condition 4. Last but not least, this is optional, but gives you a huge advantage: Mana reduction or acceleration.

Only time I won when going first was against a mill druid who probably drew very badly...
I actually win a lot when going first actually vs most decks. I just run Innervate, Barnes, and Deathwing Dragon. It just takes one good Barnes and you win. It just bullies things like mill decks and even discard lock will lose if you get a good hand to crush them quickly.
It's turn 3 i drop 3 tinyfins, i hover over every one of them slowly, my opponent gulps and is on edge of his seat, whats next you ask? I call the elven archer executioner squad drop them and hover over tinyfins again i swiftly click my hero and say "your soul shall suffer" then execute every tinyfin one by one infront of my terrifed opponent. My mage opponent snaps at turn 5 drop 3 Sorcerer's Apprentice and commits sudoku in order to stop the madness.
Although I did try some other fun stuff like different variants of single target (i.e. hex) + AoE or protect the king + Yogg or Dr Boom. Also, there is something amusing about an opponent with 7 hexed minions and no way to clear them.
