love the reaper in quick mode. It has been taking out decks probably 80% so far..
I run Moonlight, Moonlight, Reaper, Reaper, Abyss,Pitfall
The moonlights get a target down nice and juicy for the Reapers to take em out. If the moonlights get blocked( you dont usually see 2 unit stoppers) The 2 Reapers are there to ensure a Reaper kill. Then my Abyss and Pitfall to protect for a few rounds.
