[2020] Royal API has Rage at 1% use, 18% win and has Heal at 0% use, 17% win in Grand Challenges. Neither card is good or useful. Why not blend them for a small, cheap "Boost" that minimizes both cards effects?

We actually had this at a potential rework but it got nixed pretty early. It makes sense if you are already familiar with Rage + Heal spells, but to new players it's really unclear, especially if you have both the yellow and pink circles. They would also need to last the same amount of time, which is big nerf for Rage but a big buff for Heal. Good creative thinking, but sadly this didn't survive playtesting.
