converted cycling into a cost type to bring it more inline with MTGrules {cycle}, also added the cycled trigger @cycled(tc):

this cost type sends both the event for discard and the event for cycled trigger, it no longer automatically draws a card, that is part of this cost ability instead.
standard cycling is autohand={cycle}:draw:1 controller
its trigger is
auto=@cycled(*|myhand):damage:2 target(creature)
"whenever you cycle a card deal 2 damage to a target creature."
