Bold Red font for alchemy changes, including mana costs
How many times have I prismatic ending'ed an Ocelot for 1, or a 3feri for 3? I don't even know. It's 3FERI, not 4feri! If you don't want to back down from alchemy, at least make us not LOSE A COMPETITIVE GAME because of it. Make, say, a glowing border around alchemy cards (red for visibility? gold because its alchemy? blue because I like blue?) that remind me every time not to spend 3 mana on it. You might say "But, theres a giant popup blocking your screen if you try doing that...". It doesn't show up when tapping manually, which is something I have always enabled. So either make it show up every time, or implement some other way of letting us know that alchemy has ruined a perfectly fine card, because some of us might still play paper.
