I do quite like Lose Focus. I'm not a big fan of 1UU counters, but having the option to play it for 1U a lot of the time and only needing to pay 1UU later in the game is quite nice. It's also never completely dead in the very late stages of the game as you always have the option to pay 1UUU if the opponent happens to have 4-5 mana left after casting a spell. In niche cases it's also theoretically possible to counter multiple spells at once, even though that option will rarely be useful, but it doesn't hurt to have that option.
Sinister Starfish: Blacks 2 drops aren't it's strength. I think this colorshifted version is quite decent in black.
Hard Evidence: Kind of similar to Thraben Inspector. I do definitely like it. Blue doesn't have much to do on turn 1 and geting an 0/3 that early can save you quite a decent amount of life points from incoming 2/Xs.
So full spoiler is out. Other interesting card from the last wave: Storm God's Oracle: Decent body and pretty hard to get a good trade for the opponent. Even against Pacifism you can simply pay 3 and still deal 3 damage. Bannerhide Krushok: A 4/4 trample for 4 is already really good and Reinforce and Scavenge on top certainly doesn't hurt. Tragic Fall: A stricly better Last Gasp.
mtgs is such a crappy site tbh. it will take days until they update their cardlibrary. so ive no idea what cards youre talking about al
They've actually gotten a lot faster, but as always the last spoilers come in bulk, which takes a while. In hindsight, I should linked pictures, but for now you can look em up here: http://mythicspoiler.com/newspoilers.html
