there are 6-7 duels with agood necro and to show how to duel necros.
For super defensive ones use your new widowmaker to make them come to you.
as for the ones that IM you
you tele zerk them ,and if they happen to be summon necros you should use IM wand , leap them out of minin stack and tele ww.
I am not xpert on necros as i havent met many good ones ,so some of the advice i gave you might not be very accurate
Sorta OT: How do you telezerk? You lose NL when you tele so I dunno how that goes :/
well i cant tell if there is a way to do it i had to do it only afew times so id nl tele on top and zerk, this doesn't mean its the right way to do it because the guy i dueled was pretty inexperienced...
