My only problem with the reference is that there's an odd number of colours in MtG, where as we have an even number, and even then this number provides mana for sixty percent of the colours.
Your card provides mana for 33 percent of the elements, while denying another 33 percent of them, and ignoring the last bit.
Also, there is an entire story and in depth history behind MtG, but that's not the case with elements. The flavour of their cards gives explanation behind cards like this that appear to favour one group of elements over another.
Unless the other cards are implemented, that still leaves this one to be fairly out of place.
Also, if I created an aether card that provided quanta, it would either provide quanta for one other element, or some other number that can be multiplied into twelve. 2 3 4 6. Eight just seems random and out of place.
