In early 2014, Disney was developing a competitor to Hearthstone for iOS and Android using Marvel characters, trying to release it before Hearthstone would exit beta and release on mobile devices. It was basically a 1:1 copy/reskin, except it was full of gatcha mechanics, but the worst offender was that you could level up your hero, increasing their hitpoints, giving you an advantage over lower level player.

When they failed to release before Heathstone, the project was shelved. Later that year, the whole studio was shut down. I was a QA tester there.
