I only listed some...
not all...
and if u list all the mythology cards...
If you insist...
Mythology:
All Dragons and Nymphs are here, so that's 24 cards
Mindgate has some roots in mythology
Immortal fits mythology easily.
Quintessence gives immortality, sort of, so that belongs here.
Animate Weapon.
Wyrm is a type of dragon so that belongs here.
Voodoo(who do? you do!) Doll fits here.
Drain Life goes here.
Vampire Dagger obviously.
Along with Vampire.
Gargoyle too.
Liquid Shadow can fit since it gives Vampirism sort of.
Skeleton barely fits since it's more of a reanimated skeleton.
Skull Shield can fit here too.
Soul Catcher would probably work here.
Mummy would go here.
Gnome Gemfinder, gnomes are myths right? *nervously eyes my garden gnome*
I suppose Stone Skin would fit here along side Basilisk Blood.
Hematite Golem works.
Enchant Artifact definitely..
Graboids and Shriekers.
Fallen Elf.
Abomination could go here.
Lycanthrope most definitely.
Fire Specter since it's a...specter.
Rain of Fire feels like it would fit here.
Phoenix, another obvious one.
Fire Bolt works nicely here.
Rage Potion too.
Lava Golem.
Chimera and Titan
Otyugh might fit here. I'm sure there is some sort of mythology on something similar.
Armagio, just because I haven't a clue where the thing would go.
Graviton Fire Eater would probably go here.
Cockatrice and Heal(but only because it's a spell)
Forest Spirit...because it's...a spirit.
Guardian Angel(whether they exist or not isn't really the issue, it's just that they are a strong part of mythology)
Pegasus.
Ghost of The Past...since it's a ghost.
Anubis is a great candidate.
Ice Bolt fits here.
Trident belongs here.
And probably Blue Crawler.
Total: 70
Science:
Steam Machine. It's definitely part science.
Also Spark | Ball Lightning.
Lobotomizer | Electrocutor feels rather sciencey as well.
Fractal is definitely part of the science area, even if it is a spell.
Same goes for Parallel Universe and Thunderbolt.
Thunderstorm | Lightning Storm fits science, since it's technically a part of meteorology.
Shockwave has stronger ties to science.
Unstable Gas is science like, somewhat referring to gaseous elements that can explode.
Fog | Improved Fog falls under that meteorology aspect.
Eclipse falls under the astrology science.
Arsenic is also an element on the periodic table, so therefor, science!
Virus is definitely sciencey.
Plague too.
Aflatoxin feels sciencey, though that's a toss up really.
Poison | Deadly Poison fits science.
Earthquake fits science.
Mutation is all up in science's grill.
Same with Discord.
Dissipation Shield/Field could fit in science.
Fahrenheit is science.
Acceleration | Overdrive is sciencey.
And Momentum | Unstoppable.
Don't forget Gravity Pull/Force.
Mitosis and Adrenaline are definitely science.
Luciferin is sciencey.
And Photon | Ray of Light
Catapult.
supernova
black hole
antimatter
butterfly effect
maxwell's demon
schrodinger's cat
Total: 35
And then there are a lot of middle grounds such as cards based in reality. So that gap isn't that big, when Elements is an Online Fantasy Card Game. Fantasy being the keyword.
