I'm wondering if it'll be possible to implement a way of giving players some degree of control over what phantom cards they get. With only default decks for three domains, the release of borderlands has made it even less likely that the phantom card I get is playable, isn't it?

I've tot about that before.

How about it is based on the domains you played in the game?
Like say you play a DL/MF deck, you have a higher chance to get either a DL or MF card.

Why higher but not absolute change to get DLMF?
Cos i believe random phantoms do help increase a player's knowedge on cards out there and diff strategies.

Before borderlands, it was 25% for any colour.
So say i play DLMF, it increases the chance to 40% DL, 40% MF, and 10% for the other respectively. Or if single colour, 50% DL 16.6% the rest etc etc.
Some kind of formula that still leaves room for new cards!
