If you’re willing to do such things, consider house-ruling “ You may include Preparation upgrades from any aspect in your deck.” onto Natasha.
Barely any have been released in the time since the deck came out and I find that this gives a breath of fresh air to the hero, feeling like you have 1 or 2 new cards to put in builds. Obviously it is a buff to the card, but it’s something to consider playing around with if you just wish there was more preparation support.
