NEW SPELL Resurrection SPELL

Hi guys.
I am here to share my idea of a new spell named Resurrection spell.
which would bring the dead troops back to life in limited time period.
the spell needs to be used in a area where there are number of tombstones.
this spell gets unlocked at town hall 5.
cost of this spell is 25000 exilir
at level 1 spell it can only bring back barbarians to life for 20 seconds. units spawned 5 barbarians
at level 2 it costs 30000 exilir it brins back barb and archers to life for 22 seconds. 7 barb's r 7 archers
at level 3 it will bring back gaints back to life for 25 seconds. 2 gaints or 5 archers or 5 barbarians. cost 35000
at level 4 it will bring back wizards and dark exilir troops such as minions r hogs. 15 troops can be spawned for 30 seconds. cost 50000 exilir 25 dark exilir.
however starting from level 2 the spell needs to be adjusted to what it has to bring back to life..
happy clashing everyone

Posted so many times now in the forums.

And, the duration of it is too OP considering also its ability also.
