Template:Magtheridon (boss) strategy
Please add any available information to this section.
Divine Rager works well since it's Divine Shield allows its 5 attack to be used against two of the Manticron Cubes which Magtheridon auto-summons.
Only 4 attack is needed to get past the Rusted Voidwalker whose Taunt will protect the cube: this should be done in a single turn so they can't heal.
The 
Deadly Shot of the Hunter or the 
Snap Freeze of the mage is one way to take out the Cubes early on without trading minions against their tough 3-attack.
Rogues can manage this with Assassinate, Warriors with Execute (occasionally Brawl) and either with Coerce.
A Warlock can corrupt 
Cascading Disaster twice to take out all three. Twisting Nether can also do the job later on.
Paladins can combine Pursuit of Justice with 
Warhorse Trainer or Balloon Merchant to get high-attack silver hands, while Warlocks can take the path of 4/4 Lackeys though it can take time to work up to it.
