I'm not a huge Vortex player but a this is good deck to complete the current Fhtagn Ld missions (you only have 7 days left!).
Sunder, C Wing, Dregn - They will all help with the final mission of removing life.
Galen - For the Galen mission
Deea, T Gaank, Cyb Lhia - All very solid cards
Then either Qorah, Kobalth or Dreadlash to fill the remaining spot.
Comes in at around 52k, just over your budget. Dregn isn't necessary, just he would speed the final mission up.
