The problems with reactive play using Remake are that a) a single play of Remake decreases your handsize by 3 cards and doesn't help generate any sort of buying power, and b) it competes with Mountebank in the terminal slot. So while your opponent was enjoying playing a Mountebank nearly every turn for a +$2, you had to hope that you drew Remake with cards that you wanted to trash and did not get any additional buying power out of it. You can imagine that once your Remake fails to connect, or your Alch chain breaks, your momentum comes to a halt.
