To start of with: yes, it's intentional this thread only includes Parasite, due to it's high attack and due to Eclipse Bloodsuckers are fine attackers, Parasites on the other hand, are less liked by me. With a measly 1|1 and an ability that is not even in-element Parasite is probably the worst Darkness creature there is. Let's compare it with a few creatures:
A 1|1 creature with a useful, off-element ability. Light and Life have good synergies just like Death and Darkness. Rustler's ability is less dependent on the opponents' strategy but Rustler can't benefit from Nightfall/Eclipse, hence I think it's fair to say their usefulness is about equal,
yet Parasite costs twice as much quanta!A 1|1 creature that is next to useless, much like Parasites. Indeed, if Skeletons were balanced so would Parasites probably be, one extra quanta cost to get a useful ability at the cost of a weird passive. Yet this card is rarely played as a stand alone, one mostly uses skeletons when produced by Boneyards, or just for the lulz.
I hope you'll agree with me that Parasite needs a buff, Personally I'm thinking about 3 options:
- Decrease quanta cost to 1 : Since it's expensive for it's cost a cost decrease seems a somewhat logical choice, although I could foresee certain complications with Darkness gaining it's first 1 cost creature. Decreasing it's attack by one in the process could possibly balance that out.
- Increase attack to 2: Since Bloodsuckers already have 3 attack the only increase could be an increase to 2. Although it does not have my preference that might be exactly the reason that it might be reasonably balanced: since I don't mind strong Darkness creatures :P
- Increase defense to 2 or 3: This would make the upgrade a tactical upgrade, which are my favorite kind of upgrade. Defense is less useful than attack overall, but when you merely use Parasites for their ability defense is definitely preferred.
I'm personally in favor of increasing it's defense.
