This is a really minor one.
When I use a "recruiter" (
Enlistment Officer,
Sylvan Messenger,
Tidal Courier,
Goblin Ringleader,
Grave Defiler), I don't get to see the cards that are revealed from my deck (other than the recruited type, which go into my hand). I do get to see the revealed cards when the AI plays one of them.
Arguably, this doesn't matter (it's not like you're gaining much info by seeing cards from your own library that are then dumped on bottom), but there are (admittedly rare and contrived) situations where it could matter. For instance, if the last copy of a card I'd really like to topdeck just got put on bottom, then now I know that I'd better tutor for it, instead of waiting and hoping it shows up in my next few draws...
Even nitpickier - I should get to choose the order in which the other revealed cards go on bottom...
