So I played against this last night, and found it crippling. I'll fully acknowledge I 1) made poor list building choices 2) didn't respect 4 Winds Kidnap with Up We Go 3) Had poor target selection 4) Played all together significantly worse than my opponent at what i consider "normal" for me
That said. Shenlong has a massive flexible keyword that allows him to do many many things well, and combing that with near endless cards to cheat makes him a terrifying prospect to overcome. In the 1 and a half(?) turns we played, i counted at least 20 cards drawn over the course of using the Koji/4 winds/totem/Shen combo. I resigned roughly in the middle of T2, after I had lost my master (Title Viks), Taelor, and Hans was at 1 wound.
My opponent was able to use 13s 5 times in the first have of T2, while continuedly keeping his hand at 6 cards. A hand of severes, coupled with Ch (+2 to duel total) left him consistently at a 19 or better on his attacks (or defenses) with Shen, while the 13s were able to be dumped into Futahso's/Wind golem's attacks without any recourse on my part.
The 20 cards drawn include me spending a stunned AP on the viks to bonus action remove all scheme markers in range - so this name, had i not done that, would have been at least 4 higher; my opponent also elected to use Shen only attacking T2, rather than drawing another 12 (4 per attack) on his activation.
I resigned when he had killed my Leader and other primary beater, and still had a hand of severes (he told me as such) without even using the totems T2 to draw additional cards. So, 20 cards (at least) drawn in a combined total of 21? activations in the entire game before we called it. It was a legitimately unfun experience that had my opponent apologizing to me.
I do not know what the fix is; but something clearly needs to be change. Is it distruptable? Yes, I could have dove Viks in 1st activation of the game and theoretically could have killed a totem or 2 and that would have cut the engine, but in my viewing, outside a extreme hyper alpha (which without a easy focus engine i did not bring) it is a coin flip at best to pull off. If I had done so and it failed, now my Leader is inside his crew while he draws a dozen cards.
Does Protection Money need to 1) Not Stack? 2) Be Once Per Activation? or Koji 1) Enemy Only?
