1. A system for actuating two or more engine valves in an internal combustion engine, the system comprising:
at least one motion source configured to provide a plurality of valve events, the at least one motion source including a first motion source configured to provide an exhaust main valve event of the plurality of valve events; and
a valve train configured to convey the plurality of valve events from the at least one motion source to the two or more engine valves, the valve train comprising a lost motion component configured to selectively convey at least one valve event of the plurality of valve events from the at least one motion source to at least a first engine valve of the two or more engine valves;
a phasing assembly configured to selectively advance a phase of at least the first motion source so as to advance a phase of the exhaust main valve event,
wherein the at least one motion source is configured to provide a recompression relief valve event to at least the first engine valve via the valve train and the at least one lost motion component when the phase of the exhaust main valve event is advanced.
