Shademaster:
The best combo against Shademaster Kiryn that I've found so far is a
Blitz/Deflection/Kick S/S Flayer Youngling(325 speed)(A 260 speed flayer will do fine also, but anything past 272 can kick the mech and go first)
Tidal Wave/Leech Seed Terrible Turnip
Demolish/Deflection Anubisath Idol
Just kick his Giant's Blood(which he uses on CD), grind him down with the Flayer and don't bother using Deflection.
Your Flayer should be at decent health when you reach the mech(600+ish), Deflect his first move(which is Call Lightning, Kick the turret(comes second) and just Blitz.
Once your flayer dies, Turnip uses Leech Seed and grinds him down with Wave also destroying the Turrets.
Your Turnip should win, but might die - not too much of a hassle if either happens.
Anubisath gets to nothing till after Prowl, Deflect and then just smash him.
You can also use Stoneskin since there is nothing to do in the first 3 rounds anyway.
