The strategy for Maexxna seemed to be straightforward. Since his hero power was to send your minions back to your hand, the most important thing the minions you summoned needed to have was a beneficial battlecry. Also your minions weren’t going to be on the board so you needed to win with direct damage. I went for a healing/damage mage build with lots of freeze spells to handle the minions. Here’s my final deck:
- Ice Lance x 2
- Voodoo Doctor x 2
- Frostbolt x 2
- Explosive Sheep
- Frost Nova x 2
- Ice Barrier x 2
- Ice Block (I only have one in my collection)
- Earthen Ring Farseer
- Imp Master (this was to get extra tokens to ping face, but it turns out they would just get traded)
- Wolfrider
- Cone of Cold x 2
- Fireball x 2
- Polymorph x 2
- Dragon’s Breath x 2
- Antique Healbot x 2
- Blizzard
- Flamestrike x 2
- Pyroblast (I only have one in my collection)
- Molten Giant (I meant to cast this repeatedly for 0 mana, but I could never keep it out long enough to attack
I had to play this one three times and tweak my deck slightly. In the end, this heroic boss wasn’t hard but took awhile – I was thinking that I needed card fatigue to win. The key is to keep Maexxna’s board filled with one damage spiders and counteract that with healing battlecries. A single Antique Healbot would give you +1 health each turn, and leave you with 5 mana to play damage. In my winning game, they had 5 spiders and then played 2 Acidic Swamp Oozes which I had to handle with polymorphs. In a previous game, I tried Flame Strike board clears but that backfired because then he would start playing stronger minions. By keeping Maexxna’s board full, he eventually had a full hand and kept burning his draw.
I almost ran into the same scenario where my hand became full with board clears and minions that would end up being traded with spiders (e.g., Voodoo Doctors) but luckily drew Fireballs and Pyroblast to finish him off.
