Deck Concept:
When I found out that -1/-1 counters were in Amonkhet, I knew that I wanted to do a +1/+1, -1/-1 counter deck. So here is my attempt. The deck is based around Hapatra, Vizier of Poisons and Throne of the God-Pharaoh. With the tokens you get from Hapatra, Vizier of Poisons when you put -1/-1 on an opponents creature I figured Throne of the God-Pharaoh would be a fun play on that. Destroy or diminish your opponents creatures with -1/-1 counters while you beef your creatures up with +1/+1 counters.
Offense
The main source of offense is coming from Yahenni, Undying Partisan and with all of the -1/-1 counters going to your opponents, he has the potential to get big quickly. There are a couple other big creatures in there for some offense Decimator Beetle & Verdurous Gearhulk
Defense
The defense mostly comes from the -1/-1 counters (Hapatra, Vizier of Poisons, Liliana, Death Wielder, Decimator Beetle, Splendid Agony), but there are also some instants to slow down your opponents in the beginning. Fatal Push is always good in the beginning of a game. Subtle Strike is good for some defense while also getting a +1/+1 on your creature. I also have Manglehorn in the sideboard for an artifact based deck.You can also use Animation Module's effect to add -1/-1 to your opponent's creatures for some -1/-1 ramp.
Tokens
Animation Module, Hapatra, Vizier of Poisons, Oviya Pashiri, Sage Lifecrafter, Noosegraf Mob, and Second Harvest are all token vehicles.
That is my idea on this counters/tokens deck! Let me know what you think.
+1 if you like it, comment if you have a suggestion!
