play style - t1 - hold the horesemen back in cover, moving forward 2-3"
t-2 - move horsemen forward to beyond 6" to start laying markers
t-3 - go agressive with 3 horse men to pick off advanced enemy models, 4th positions to drop markers near enemy deployment zone
t- 4 - 4th horsey drops markers and harasses enemy back line (pale rider is good for this) , mechanical rider creates a minion to drop a scheme marker and reactivates another horse man ( maybe pale rider to get another marker )as needed
t - 5 hooded rider does the judgment bomb, dead rider targets enemy master of henchman and atempts to horrify , mechanical moves, markers and reacivates, pale rider kills stuff and the minion moves and markers ,
this is all dependant on scheams ect and leaves your master free to cause havoc with the enemy - just my take on what i do with riders
