i guess my point was less on the randomness or non randomness of the card but rather a suggestion of a mechanic effecting which side of the field a card is played on, in order to act as a method of control or denial. as far as randomness being an entropy only characteristic, what about fog shield or dusk mantle? i think as long as you can tailor the theme to the element there should be no requirement of entropy for randomness to be involved.
