#1 = Photon
"Some science thingy"
Fair, although it's not good. This doesn't tell you much, I could just as easily fit Mitosis if it wasn't for the fact you're given the number of letters.
Made me laugh. 
#2 = Werewolf
"Oh how high the moon!"
It's a fair clue but doesn't get you straight into the answer─In fact, not even into Entropy─ it's a misleading clue to Nightfall/Eclipse, although they don't fit. I like clues like this one although I did have to get some thought to get it right.
I considered it pretty good. Almost poetic, in a kitschy way.#3 = Miracle
"Wonder of wonders _____"
Again, fair clue, although it is confusing with that line at the end. Getting rid of the line gets you where you need to be.
Agreed.#5 = Giant Frog
"make sure you look both ways before you cross the street"
Okay, I get it, but this is a bad clue. It could just as easily be Toadfish and a number of other creatures that have their eyes in that configuration. In the end, I had to guess using other clues.
There was this old game called Frogger. A fair hint.#7 = Lobotomizer
"ouch"
... What?
Yep, my first thought was it'll be some sort of hard CC, but if you know what is lobotomization, then you'll agree that it's an 'ouch' thingy.#8 = Mitosis
"_____ very pretty".
Again, what?
Maybe it is just a very bad pun. "My toes is very pretty." Also.#9 = Improved Mutation
"Hey, it's the new me!"
I don't know why you would pick Improved Mutation over Mutation other than to get everything in the crossword together. It's a confusing clue. This one got me really stumped until I tried to guess using other clues.
My first guess was Procrastination, but that was too short. I was pretty sure about the '-ation' ending. It wasn't that hard for me.#10 = Dry Spell
"Guys, have the ladies been rejecting you a lot lately?"
...
No comment. Bad clue.
Bad clue in a way that it isn't straightforward, but after checking the solutions it made me laugh. (I skipped like 3 lines, frustrating ones made me tired.)#11 = Steel Golem
"Put us in your shopping cart. We're a real steal".
This clue is a pun. I like puns but it's quite confusing, especially when there's a card called Steal in the game.
I was thinking in cheapo creatures, that made it easier.#12 = Pest
"RNG is a ____"
Confusing clue. You don't usually put that at the end of that sentence. RNG makes people way angrier.
Yep, strange choice. My first mental association was 'bitch'. 
Had to find an euphemized swearing in the game.#13 = Pharaoh
"I prefer double ply"
... What?
I was stupefied, too. Thought that there is a toilet paper brand 'Pharaoh', or something like that.
But know, in retrospect here is a possible logic. Mummies are covered in gauze - which resembles toilet paper. Pharaohs turn into Mummies (in real life).
Don't have a better idea. #14 = Retrovirus
"Back in the day, disease was cool".
This one speaks for itself. I like this clue.
hehe:#17 = Black Hole
"Ever wondered what was in there?"
...... What?
Haven't it occurred to you what Black Holes really are?#18 = Stone Skin
"Jealous of our tan? Why don't you try baking in the sun for hundreds of years."
Same as #16. Lazy clue that isn't great. The only part that actually gives it away is "tan".
Not that bad, imo.#19 = Minor Vampire
"I'm sorry, but you're too young to suck"
...
No comment. Very confusing clue.
Actually, I found this one quite logical.#20 = Blessing
"Mazeltov"
Had to do some research to get this one, and even then, it got me stumped. Fair but not great.
Likeable for me.#22 = Spark
"!"
...
No comment.
Yep. #25 = Unstable Gas
"Potent fart"
... Seriously?
Well, I also like to call Blue Nymphs Farty Nymphs. #28 = Discord
"Come on, can't we all just get along?"
Fair, but confusing.
That's what Discord has to do! I was kinda happy that Discord wasn't "banned" from this puzzle. #29 = Cloak
"I need to conceal this pimple. what should I use?"
Same as #28, although this one is fairly less obvious.
Conceal...#30 = Phoenix
"I'm related to yeast".
... What?
Just joking again. Phoenix reborns/rises, yeast too. Understand your frustration I was a bit mad about it, too, but gotta admit
it was sort of a good pun.#31 = Colossal Dragon
"People don't trust I can take off in flight. That's why they don't use me in decks".
Lazy clue overall that doesn0t get you anywhere. Had to guess by other clues.
I was thinking about a heavy flyer. Imagine the old picture of the Col. Dragon, hehe. #32 = Psion
"Everytime someone complains about RNG, it's time to get my ____"
I... don't really get this one. What?
Maybe a pun? "Sigh on?" Dunno.#33 = Wings
"Where ____ take dream".
I don't think this is correctly written. Confusing.
Google says: George W. Bush quote.#34 = Steam Machine
"James Brown"
I don't get this one but maybe it's something I'm missing. After all, I don't know who James Brown is.
Too bad. The godfather of soul. The "Sex Machine". Do some googling, it worth.
