Caught! Mike Donais Helped Redesign a Magic Card for Hearthstone
A thread on reddit created by cromatkastar early this morning titled "'Can I copy your homework?' 'Sure'" got itself a response from Hearthstone's Principal Game Designer, Mike Donais. Cromatkastar pointed out that the new Violet Wurm card was exactly like a card from Magic the Gathering - Symbiotic Wurm.
Mike came in and noted that he helped design both Kobolds & Catacombs and the 17-year-old Magic expansion the card came from - Onslaught. That's a pretty impressive history!

Quick Question: Is it still copying if I designed Symbiotic Wurm for Onslaught 17 years ago and then designed it again for Hearthstone?
(That isn't exactly how it happened but I helped design both expansions and it makes a much better story.)
