Triple Triad With A Twist (working title)

Had an idea for a card game based on Triple Triad (see title).

I thought it would be interesting to try to come up with a mechanic where you wouldn't end up wanting only the cards with the highest numbers.

In this version the corners have a light and dark setting that takes effect only when you move them to the table, meaning they beat equal or lower if dark and equal or higher if light. After attacking neighbouring cards, the effect chains onto the next card.

I don't really know whether anyone remotely has a chance of getting their head around the gameplay enough to play strategically or collect the right cards.

Should I follow it through or not?
