That's a ridiculously huge change you are suggesting there, just casually.. Right. Bad suggestion!No one is saying Heatwave is worthless. It's a great card and pretty much auto-include in the meta of blatant Caretaker abuse, but Yen should either be at least the same provision cost, OR the ability should be changed to something like "If it's NG unit, place it on top of your deck. All other factions: place the unit on the BOTTOM of THEIR deck."
Anyways, why not consider lowering the provisions of heatwave to the same as Yen, instead of raising her to the same as heatwave? Or just swap the 2 provisions.
