Yes, that was indeed an amusing combo. Nowhere near the largest combo I've ever seen - probably not in the top five - but definitely in the top 10.
For reference, the top two combos are:
23 distinct cards (70ish total cards required, plus a large number of tokens and copied spells): the current version (v5) of My Turing machine, proving Magic: the Gathering Turing complete.
60 distinct cards (and only maxed at 60 because they limited themselves there): SadisticMystic and metroidcomposite's megacombo. Dealing far more damage on turn 1 than there would be atoms in the universe if every atom was in fact an entire universe, but without any infinite combos. A piece of terrifying wonder.
...I should really get around to updating my Turing machine to the version without any "may" abilities. Omen Machine / Wild Evocation allow forcing casts of spells, as long as I completely restructure to have each step be a full turn cycle rather than everything happening in one phase. I'm pretty sure it all works, I just need to write it up.
