killing your second double>?

[Razorflame]

the first double i did with no losses

(had shaman/beholder/demoness/inqi's/necro ^^)

i thought i was gonna lose this battle hard(since i forgot to use a weak army)

but to my surprise i could kill him easy)

but then came the secodn double

the units i used in the first battle were impossible to win (playing as mage)
so i used a stack of all weak units spiders/demoness/peasants/thorn warriors and hunters

first rain down rain of fire on the thorns

but still the bastard had alot of other units 5k+ peasants O.o
with every hit they done they kill 1 of my stacks lol ^^

eventually i won the battle (but lost allmost all), safe for demoness

and some peasants
how to do this easy>? ^^
