Latest rendition of my +1/+1 counter deck. Still fairly new to this, so any suggestions are welcome.

The idea is to find Primordial Hydra using Jarad's Orders, putting a scavenge creature into the graveyard for later use. Then I'll use one or more Corpsejack Menace to pump up Primordial Hydra, possibly putting an Alpha Authority on Hydra. Then, depending on how I feel, I'll either swing for lots or use Essence Harvest. Alternate win conditions involve Wild Beastmaster pumped up with +1/+1 counters and slowly draining opponents with Vampire Nighthawk. Predator's Rapport is in there just to intimidate my opponents if I feel like it.
