I think that either choice of Frontier or Academy would be a great name. They both make it clear that it's for beginners, but they both have a different flavor. Academy emphasizes the training aspect, whereas Frontier emphasizes that this is kind of the first steps to the broader Splinterlands experience. In either case, I think the free-to-play experience is something that is essential for new players. It was so disappointing to jump into a modern match for the first time and get completely blown out of the water by decks that were way more powerful than my Foundation set.
