I may sound stupid here but who is cortez?
Inquisitor Coteaz is a special character in Codex:Inquisition that has a special rule allowing him (and his unit) to shoot at a deepstriking enemy unit within 12"; he can do this infinite times each turn. Throw him in with a melta squad etc. and deploy him well and he will eat up your opponent as he tries to bear dowon on you. The inquisition detachment is 1-2 HQ (inquisitors) and 0-3 Elites (henchmen squads), so you could just take him if you wanted.
