good, but overpowered
if you run Water, and throw a few pillars, and play this, you can get a lot of quanta very easily, powering shards or your creatures or whatever. It is very, very strong. Have it be 3 every other turn or something, but 2 every tyurn of unchanged is too much. It also has potential for abuse... consider you have X quanta of some type. you use abilities that cost 2 of that type. this, if played in the right order, sees that as being the same, thus generates free quanta for that element. in other words, you can manipulate this into generating quanta you did use, instead of just filling gaps. I like the card a lot, but it is a bit strong... its cost is good for the ability, but it is just too much strength with few counters.
