I’ve set up a proxy set with @EricF 's proposed changes, and a few of other suggestions from Nudging the tiller - balance - #205 by flagrantangles and Blue balancing suggestions - #88 by GRAG sprinkled in.
Full list of changes here
First few test games netted following:
Game suddenly has a very fresh feeling again 
Blue:
- Constable at 2g is very playable. Did not feel too OP.
- Musketeer that keeps LR at 2 ATK is much more relevant since combos with Elite Training and Bootcamp. Did not feel too OP.
- Jurisdiction that peeks at hand felt good to play, strong yet fair. I think that one is spot on.
- Search Warrant is pretty awesome and fair.
Green:
- Midori suddenly is much more of a threat. Tokens, too. Very interesting gameplay resulted. Felt strong. Might be OP, not sure.
- Giant Panda at 3 ATK felt relevant, partly due to Wisps being better.
- Did not notice much of a difference with YT able to attack, but being limited to 2 ATK.
- Rich Earth felt good.
Red:
- Flame Arrow at 3g felt strong. Not sure if OP.
- Fire Dart at 1g felt very strong. Might be OP.
- Scorch did not come into picture.
- Zane giving 2g instead of 2 levels felt decent.
Purple:
- Sentry is supergood now. Not sure if OP.
- KotC at Forecast 2 felt good, especially since Time Spiral is 0g now. I went balls deep into spamming things with time runes + 2xSeer + Temporal Research, felt cool, unusual and strong. This build was never able to take off for us before. Not sure if OP. KotC might warrant 1g cost.
- Prynn midband always proccing on death felt a bit degenerate. Putting her in SQL was too good
I’ll give her more chances though.
That’s it for now. No Black, White and Renegade games yet.
