Achievement help

Hey everyone, I found a nice deck to get all the "speedy" achievements and I wanted to share thisa with you.
It's very easy to build:

Malort
Mawcor
3x Asylum
+2 Action cards with strike (in my case I used Airstrike and Death from Above)

That's all. Just play Mawcor in the first round and you should get the achievement after just a few tries.
------------

I also built a deck for the different "annihilator" achievements:

Duncan
Malgoth
Tiamat
Gun Raven
2x Aegis
Missile Silo
Orbital Cannon
2x Multi-Strike and/or Death from above
Sulfuris Acid Pit

You need to get your opponent to play every card, thus you need to slow down your victory because he has 3 extra cards. So I included 2 cards with high health and low damage (Gun Raven and Malgoth). Duncan deals with the structures, but if you're having a hard time you could also swap the Orbital Cannon for any cards with siege. Since Gun Raven and Malgoth have a low attack, I included many strike cards to deal with the opponent's defense. Aegis will keep your cards alive.

I've been able to complete each of these achievements so far, except for "Xeno Annihilator". So if anyone knows a good built please let me know.
