As the name said: there are two main focuses in this deck:
Phyrexian Obliterator + Arena OR Phyrexian Obliterator + Ulvenwald Tracker to let opponent sacrifise
Mimic Vat to reproduce important units of opponent
Synergies: So how that works
reproduce important units of opponent
The main idea is to use Mimic Vat to take the best out of your opponent.
T1: land. Play Ruthless Ripper or Typhoid Rats
T2: land. Play: Birds of Paradise and Ruthless Ripper or Typhoid Rats
T3: land. Play Mimic Vat and Ulvenwald Tracker
T4: land. Use ability of Ulvenwald Tracker for to let your deathtouch creature fight anyone you like and reproduce for with Mimic Vat.
let opponent sacrifise
T1: land. Play: Birds of Paradise
T2: land. Play Chromatic Lantern
T3: land. Play Phyrexian Obliterator and Ulvenwald Tracker
T4: land. Use ability of Ulvenwald Tracker for . Then Tower Above and go to combat.
==> opponent has to sacrifise if he has a creature played you can target. Normally it is not big enough to kill your Phyrexian Obliterator.
Now you should have a good advantage and attack every round for 5 as long he is not destroying your Obliterator. He will force that ;)
if he is playing with deathtough you have to target a non deathtough creature OR
combine strategies like this:
T1: land. Play: Birds of Paradise
T2: land. Play Vampire Nighthawk
T3: land. Play Mimic Vat + Ulvenwald Tracker
T4: land. Play Phyrexian Obliterator and use ability of Ulvenwald Tracker for on Phyrexian Obliterator.
Same effect. This time you can secure your Phyrexian Obliterator via the Mimic Vat. This is even a boost due to the fact that you can play every round an Phyrexian Obliterator.
Also working: try to play a Primeval Titan in T4 and bring an Arena into play tapped. From next turn on you can let a creature fight every time _and _ you have enough mana to do everything you like.
Do I have to mention that bringing a Primeval Titan every round with Mimic Vat is even more horror ;)
