lol
don't use damage spells all the time
you need crow control
and it's quite easy to troops together
the art is to cast invsibility
and then place a demon portal with magic spring on it*(in other words the scagoat)
the first 2-3 turns can be used to use damaging spells to let your demon portal unit live longer
but keep casting magic spring on the bug and invisiblity on your egd
and without the 8 ini u have a hard time
magic spring+mana drain=unlimited mana
