The problem with this is that not all decks with a certain mark would synergise with their respective powers. Take this for example.
I'm not asking for feedback on this. This was taken from War #12, one of the PvP events here

This deck has no need for Quintessence (You
want to be able to target your creatures. Making them immortal takes away from that), Lightning (You don't need to kill any troublesome creatures when you can block them out with hope), or Phase Salvagers (The main permanent is already protected, so why would you need a Salvager at all?).
There's plenty of decks that use a certain element solely for one specific card (Discohole/DBH, Adrenastaves, etc.) where having an elemental power would either not be beneficial to the deck or would harm it.
