I run Garryth and Thyron in tandem if I need a "competitive" pairing. More often than not I will just have Garryth in different theme lists because well, he's the man. But if shoehorned into a 2 list format I will run Thryon in Defenders and Garryth in Shadows.
I think Kae has solid game in Shadows, against WM lists. Stun the Jacks with her shots, tag a Jack with Backlash, and pound away with MHSF.
In LoD, Sents love Blur, and again, stunning a Jack and Backlashing is good times.
Not much game against Hordes, though.
Interesting. I always felt that the fury removal on her weapon and the "no charges" feat gave her plenty of game into Hordes. I might be biased because the last game I played with her was into Una2 but magical shooting on my Phoenix and Hydra made it hard for Una to come forward and Phantom Seeker meant I constantly threatened the Scarsfell Griffons. Although mistakes were made on both sides - and my opponent had a couple of abysmal dice rolls - it felt like I was in control. I can only imagine what would happen if I replaced my Ellowuyr Swordsmen with a full unit of Houseguard Riflemen and a Houseguard Thane for a full anti-stealth list.
