The Dark Aster

Choke out both the deck and the hand with garbage.  IM and Onslaught can help DH or Ronan be stronger.  An ideal setup could be IM/DH/Onslaught on turns 5,6,7. Or Wave into IM/DH/Onslaught on turns 4,5,6. 

Variations on this could include Armor or removing Master Mold for an X-Man to boost Iceman, Psylocke and Magik.
