The answer isnt as straightforward as that of the riddle Oedipus solved, but I like how it gives this Sphinx an adventurous tinge
While tapping makes it less useful, it's a virtually unknown card and much cheaper than the least expensive printing of Karn
Meanwhile, cards that have been digitally rebalanced and have regular printings are reverted to their original text, but cards released into Alchemy that have been rebalanced retain their changes
As long as at least one creature card was discarded this way, you'll create a Moogle token, and as long as at least one noncreature card was discarded this way, you'll put a +1/+1 counter on each Moogle you control
That is entirely contextual
The first Cores Sets were Alpha and Beta, both in 1993
