Anavar is the GOAT. You can also look at T-bol and Winstrol as good cutting options. It just depends on what you're looking for. No matter what you do, make sure that you're running N2Guard with it to save your liver.
Deca and Tren are the absolute GOAT. If you want to run a shorter cycle, pick shorter esters; that is the key. If you want a longer cycle, then go longer but I wouldn't run Tren more than 8 weeks or Deca more than 12 weeks.
