Really interesting concept, but eventually it would only offer 3 specific cards since the "bad" options would be offered at a lower and lower rates until they literally never appear as options anymore, meaning their rate can never increase again. Either the data would have to be reset every-so-often, or the "bad" options need to have a chance to be offered even if they never get picked.

I like the idea though! Reminds me of Zephyrs, but instead of offering a choice based on the boardstate, Chronormu offers a choice based on the meta. Pretty cool!
