Editing Warhammer 40,000/8th Edition Tactics/Thousand Sons (section)

===The Crimson King===
The short and sweet of this tactic is easily summed up in these two words, BUFF MAGNUS!!! Take Magnus, Ahriman on disc and either daemon princes or an exalted sorcerer of disc (with High Magister trait for +1 to cast). Then, during the psychic phase, just give Magnus all the buffs you can (Glamour makes him -1 to hit, Weaver gives him +1 Invul, +2 Str/+1 A from diabolic strength, healing D3 wounds by Temporal Manipulation, etc). Magnus's 2D6 smite is your best weapon, even better than his stick - which even though is formidable, still only does 3D per hit. He can cast/deny 3/3 respectively, at default +2 to cast which can be improved by additional +2 (from Cabalistic focus) allowing him to 2d6 supersmite on 8+ roll. 

A recent tournament list used this very same tactic to a devastating effect by taking Magnus (with Smite, Infernal Gateway, Diabolic Strength), Ahriman on Disk (w/ Weaver of Fate, Temporal Manipulation, Warptime), High Magister Exalter Sorcerer on Disk (w/ Glamour, Prescience) and 9x Tzaangors Enlightened Bowmen w/ a Shaman. Everything moves as one, up the board while keeping all psykers within Magnus's 9" reroll bubble. At this point, order of casting becomes important. First, your Warlord casts Glamour on Magnus (and Prescience onto Tzaangors). Then Magnus casts his Smite (use Cabalistic focus for +2 to cast), Infernal Gateway, Diabolic Strength. Lastly, Ahriman casts Weaver of Fate, Smite (or Temporal manipulation if Magnus needs healing) and at the very, very, very end - Warptime to catapult a fully buffed Magnus in the direction of the enemy. On the charge, Magnus is at -1 to hit, with 3+ invul, and strikes with 9x Str20 Attacks at 3 damage each, hitting on 2+ (rerolling 1s). Meanwhile, the Psykers remain behind the Tzaangor Enlightened who spam autowounds on whatever Magnus didn't get a chance to tie up on a charge.

***Keep in mind, Magnus (even when fully buffed) doesn't have the hitting power or the sheer resilience of Mortation - but when you take into account the mortal wound spam during the psychic phase it equals out the damage output. Keep an eye out for any enemy Null Zone or Death Hex casting characters, because while Mortarion is capable of surviving without his Invul, Magnus most probably will not.
