League of Explorers 2.0 hates duplicate cards

No problem - my Gnome rogue still has vivid nightmares from back in 2005, when she got squashed repeatedly by King Krush in Un’goro. Much later a quest line was installed there with a hapless Stormwind knight trying to fight against “dragons” and rescuing a not-so-much damsel in distress, Don Quichote-style:

P.S. In the trivia part of your link I found this nugget about Dinotamer Bran’s creation:

This was followed by the idea of summoning King Krush, but as the developers were worried about the power of the Charge effect, they instead started experimenting with having Brann summon two 5/5 devilsaurs with Rush. This design got so far into the process that the two devilsaurs even had their own names: Duke and Duchess. In the end, however, the team gravitated back toward the King Krush version since it felt much more satisfying and because they wanted a splashy and extreme effect for Brann’s Battlecry.

Awwww - now I really want to see Duke & Duchess in a later release.

Pretty Please, Team 5?
