I just managed it with a basic deck, took me 1 day over about 4 hrs.
Im really chuffed so i thought id help out u guys if ur having trouble.
I must warn you tho, it isnt easy and it isnt fun.
It requires PRIEST and a set routine for the start.
Basically maexxna must spawn deathrattle spiders and the plan is by turn 5 or 6 you use a spell to deal 2 damage them thus creating 1/1 replacements.
now ur gonna need a little luck and a few restarts to achieve this but its fairly easy.
so what do you do between turn 1 and 5? well make sure you have these cards in ur hand or 90% of them so to speak, at the beginning. read on for details.
Stage 1. Plan for the HOLY NOVA by turn 5 or 6, in the mean time having VOODOO DR and ELVEN ARCHER are v.good starts, if you can get a 1/1 charge also it gets the ball rolling on lowering her health slowly.
I say slowly because ur gonna take this b***h out in one hit eventually, and ur gonna have to be very smart and tactful to do it.
So dont charge the minions at all, let the HOLY NOVA do that job.
the only exception is ull find that maexnna spawns other minions too, i know i know its a real ball ache but thats where ur 1/1 and 2/1 charge and Elven Archer comes to the rescue.
So early game u need to establish the board in that she has 7x 1 attack minions against you, and this means she cant play any other cards until the board is clear on her side... HURRAY.
for example she will ideally spawn 4 spiders thus creating 8 1/1's after deathrattle and jam the board. The board only takes 7 anyway but lets say she had another minion out there before the deathrattle, ur gonna have to deal with that first in THE SAME TURN as ur HOLY NOVA otherwise ur defeating the object of the tactic. Thats why i say turn 5 or 6. i recommend the HOLY SMITE card first on for example a 4/4 minion at cost of 1 mana and then HOLY NOVA to take them all out. Of course i said it was hard, and it is, to get this opening AND having these cards requires a little luck but not impossible.
Stage 2.
She will have ur health down to mid teens by this point so stage 2 is all about health..
heal urself as much as possible as shes gonna be taking 7 hits off you per turn.
Ull need PRIESTESS OF ELUNE, VOODOO DR and EARTHEN RING FARSEER.
but YOU MUST NOT use all 3 together, the most important rule is 2 MINIONS ON THE BOARD AT THE END OF UR TURN. if your serious about this tactic ull have to be patient.
Just to recap, ur goal is to allow her 7 hits per turn, heal urself and wait for the right cards to come along to finish her.
what are the cards? well its easy.. CHARGE...
anything other than a charge wont work, its got to be done in 1 turn when all ur cards have come together - 2-5 charge (stormwind knight) 2x power word shield and 2x devine spirit and inner fire. = 27 attack.
its not that impressive, and it doesnt have to be. I managed with a 14 hit to kill her but plan for it anyway. even having a ABUSIVE SERGEANT is a must.
Why is it a must.... well
Stage 3.. final stage..
most of the cards are unwanted.. u have to pick 30 anyway and this isnt good for you in this deck. ull have cards coming out and you wont be able to use them... uve got to keep ur health up and can rarly deviate. so what happens if u need a card and ur hand is full..
well, uve got to sort it out! this deck is full of spells but u will still have minion cards in your deck that u dont want and are blocking you.
this is the fun part.. be tactful, ull find a way around it.
Have fun.
