Hybrid or Psuedo Elemental Cards don't seem to last long in the Design section of the forums.
The main sticking point is it would require the introduction of a massive amount of cards which means alot of work for the developers. I propose that some the cards already being used can be shifted into this category. Another thing is combining effects from the elements but making these Hybrid cards generally very expensive
The first thing I propose is to not make creatures have hybrid quanta costs. Since they already have the option to have abilities from other elemental quanta pools to make them Psuedo Elemental anyway. Weapons can be included in that category since they basically behave very similar to creatures anyway.
So that leaves spells and shields. An easy way to make new cards would be to combine effects from 2 elements that make sense together.
Various examples:
Current Cards:
Ice Shield - Really I think this shield is just over powered. It already does damage reduction, which I consider Earth Shields specialty, with an added bonus of potentially freezing the attacking creature. I think a shield that just induces freezing can stand on its own without the damage reduction, and a Hybrid Shield of Earth and Water can be what the current but with a quanta cost of 8 and 9 random
quanta
Purify - 2
Can heal 3 HP and add Regen Counter
Black Hole - 4
It drains resources from enemy to sustain itself, just like Darkness
Thunderstorm 2
New Cards Examples
I like is taking the Fire Shield and combining it with Dusk for Smokescreen, 8 quanta costs, for a 40% chance to dodge and deal 1 damage to the creatures that miss. This means that when I creature does make it through the smoke it won't lose HP, combining the best and worst of the 2 shields. The 40% puts it equal to Fog Shield but with a much higher quanta cost
Combustion Shield, a combination of Skull Shield and Immolation, 6 random
or
quanta. A shield that has a chance of killing the attacking monster and at the same time granting the user 5 fire quanta and 1 of each other quanta.
Humidity, a combination of Fog Shield and Water costs 5 random
or
. This would be a new type of shield with a 33% block rate that generate 1
quanta when blocking an attack.
