I just bought research for the first time, and I am significantly underwhelmed.
Most duration cards are great for reliability, starting with extra stuff next turn is strong. Not so much research, if you have a strong enough engine to draw the deck and want some reliability, research can't do it. You set the cards aside when you play it, you don't draw extra at the start of next turn. All the cards that you set aside can't be played until next turn.
It isn't a bad trasher, it does fine on estates, and at least it isn't terminal for other junk, and doesn't miss reshuffles if you don't set aside cards. Once the junk is trashed though, it isn't so great.
I suppose it could be strong with storeroom, but that is a lot of work to get working, first I need two researches because duration, then I need a couple villages, and some other source of draw, and then at least one storeroom, preferably two (one to sift the junk I set aside every turn to ensure I don't have a dud turn, and one to turn the junk into coin after it is redrawn). Maybe it could be a little sleeker than that if the right enablers are on the board, but I think I'd rather have a couple silvers and golds.
