I dunno, I have a hard time considering Knight of the Conclave as notable. It’s easy on the gold, that’s for sure. But Forecast 3 with no haste means that your opponent is likely either going down on cards to get him out, or giving you like 4 turns warning that he’s going to be a threat. By then you’ll be at Tech 2 and scoff at a 4/4 with Resist 1. I mean, he’s not even as good as a Plasmodium (I’ll take Haste over Resist 1 any day)!
As you point out, Tinkerer can get you some value out of him, but that’s because Tinkerer is the notable card in that combo.
Future doesn’t really have a notable Tech 1, imo, which is one of the things that makes the spec less viable in mixed color Codexes.
