It took me awhile to get oriented, used extensive mana funneling.
Cuz, the Shaman is red, when he attack, he drains mana from all units having a red dots - in that case is secured that at worst in second round his secondary is charged. (Sure, it removes just one debuff but it also dispel Silence, Stun, Poison or Burning - which we need here.)
Shaman should go with Assasin's Tome.
As Assura can do these multiply attacks with dealing debuffs and burns, I have two more units as backup, keeping them charged.
Marid is vital, not only it can deal decent damage (9k, he's just too fresh), cast 60% defense it also can dispel one enemy buff. Which is more than enough in this case.
Now it's just balance of "left wing" Shaman's cleaning and Marid's hit to beging with or to start with "right wing" to charge Yetti and the remaining two, from cleaning staff.
When Yetti is charged his blow is deadly, going above 24k.
Of course, this is not the only strategy. But I'm particulary weak in Blue Leg deparment and limited in prismatic orbs. So you could still go with reset, stun, hit. Do you know any blue unit causing Silence?
Just a note, I have all Keeps above lvl 20, and Shrines on lvl 23/22.
