Definitely. this week is soa heavy, it's almost mandatory to have a stop: ability in your deck imo just to have a threat against the masses. Sprinter is a great threat as he can kill with no problem. Pill for pill in elo, there aren't too many cards with soa that can stop him. He's a great choice.
May be just me, but after i crossed 1200 SoA and SoB just disappeared almost completely .
I was playing Berzerk/Skeelz deck and was just facing atk.man everywhere (Uppers, Sakrohm, Rescue, Junkz, Sentinel, even Montana), Berzerk (for obvious reasons) and a little Ulu Watu, pc, Vortex and Jungo.
Because of that i tried a Berzerk/Vortex deck and it did just fine, im 1300 now. Gonna try go higher later.
