that's al whining imho
see the thread of last hero without resu/sacri/gift
last hero is your best option then
best thing is u can combine this spell with target
last+hero +target is a very nice combo
try a royal snake(i think last hero counts for level 3 so snake is level 3)
it has decent HP and very fast initive and no retalation which makes this unit perfect for the job
and try to keep up the life with an archmage shield
and most melee enemy stacks would fail for the bite and u can take an easy vicotry
