#show Lichborne
/use [@player]Death Coil
/use Lichborne
this will works, because Death Coil is actually first spell to be used in the macro and without Lichborne you can't do that on yourself
on first click you will activate lichborne, on every next will heal yourself
...
or extend it with pet coil too on ALT+key, if no modifier same from above happens > lichborne > self healing
#show [mod:alt,@PetName,nodead]Death Coil;Lichborne
/use [nomod,@player]Death Coil
