Just played a game with Wizards. They're fun, but it seems quite problematic that Student is a trasher that you can lock other players out of getting once you have it. If there is no other trashing, it's basically a mandatory opener, even on 5/2.
Not locked out; they can always just buy their way through the pile ;-)
Maybe it's me, but I don't think Student is all that overpowered. It trashes just a single card which is not that impressive, BM probably even beats BM+Student.
You have to trash Treasures to get its benefit, but in the early game Coppers are important to reach those critical $5 cards (oftentimes the critical cards are $5+), and Estates are not so you'd rather trash Estates if you can.
And besides trashing, it provides no other value, especially if the Ally isn't that useful.
The topdecking seems powerful, but when you start the game, you only have 10 cards, so say you bought any other trashing card, you'll play it every other turn anyway and increasingly often after you've started thinning.
So you are sacrificing a lot, and I do mean a lot of early game tempo if your strategy depends on Student, so your engine needs to be good enough to catch up.
I don't know if the "Silver test" is still a thing, but there will be many times where you wished it was a Silver.
