Ooh fun.
Light- Taller element, higher stats for higher price (ex: Golden Dragon)
- Healing (seems to be more oriented towards creatures compared to Life's healing)
- Is the element that deals with max HP the most
- Mainly deals with own creatures, opponent's field is mostly unaffected
Darkness- Bit wider as an element
- Vampiric is a unique feature
- Many effects of stealing (HP through vampires, NM, and Drain Life, quanta through Devs, permanents through Steal, etc.)
So, similarities would be:
- Healing
- Buffs
- Dealing with quanta (either through protection or stealing)
- Both have impressive quanta generation
Things together:
- Extremely high quanta generation
- Able to make the biggest difference in max HP (through lowering opponent's while raising own)
- Incredible healing
- Protection (Cloak, HP buffs, Sanct)
Don't share:
- Thievery
- Control (CC, PC, QC is only in Darkness)
pendulum-type card switching between Night-Day side with different effects (odd-even turn or switch on activation)
I like.
