Abstract Art:
This card will allow you to randomly gain 1 attack, lose 1 hp, or generate 3 quanta.
For 5 quanta.... which you could also spend on an Abomination.
If you hit the 'gain 1 attack' every turn, you would have it on your 4th attack (because of summoning sickness).
After 4 turns Abomination would have hit for 20 damage, this card would have hit for 14. So best case on the attack side it's a lot worse than Abomination.
Also Abomination has 5 health instead of 4 and doesn't have a 2 cost activation to generate random quanta.
If you get the 'lose 1 hp' it's just bad... really bad. 4 of those and this card is dead.
Now for the generate 3 random quanta.... that sounds great, right? It's a Quantum Pillar with attack, good, huh? It'll cost you 5 entropy to play it though.... maybe not so good. But 3 quanta is a good thing, right? Well, keep in mind you're paying 2 random quanta to get that... so you're coming away with an increase of 1. Yep, that's 1 random quanta.
Oh and not to mention, we have no idea what the % chance of getting each is. Looks more like a.... 'hmmm, I'm gonna make a creature, oh let's make it entropy and give it random things if you spend quanta.' With no thought to if any of those would be good. Sorry, Kuro should have won this round, and tbh yours should have been at 1 vote, since you liked it. Maybe not so much after reading this post.

Now to help you understand the difference between a good card and a bad one:
For a random increase in attack, you need to think about the other cards that do that. All of them are +2 (or +5 for steam machine), but those are consistent. Yours is random. which means you'll have to compensate. Steam Machine does this by losing 1 attack every turn. Lava Golem and Forest Spirit each use quanta of a different element and thus are given +2 hp when they use their ability, not to mention their fragility with 1 hp unupped.
Your card however is just 1 and at only a 33%? chance. (We'll assume it's 33% for this)
That only gives you +1 attack every 3 turns. With the Abomination example above, this would take you about 8-10 turns on average to get to 5 attack.. and by then it'd end around being a 5/2 creature that you just invested around 20 quanta in.
If you were wanting to give it interesting stats, then it could have been something like: +3/-1, -1/+2, and 5 random quanta.
With those buffs it'd be interesting to play. A couple of the +3/-1 buffs and you have a high attack fragile creature.
With a mix of 2 stat changers you'd end up with a decent creature.
Now for the quanta, it would net you +3 quanta... pretty good if you ask me, and a fun, but risky, alternative to playing Quantum Pillars.
Sound good?
