The name depends on what this mode is for. If it's for beginners then academy is fine, but if this is to be a F2P mode for all players of all abilities and stages of gameplay then Academy isn't a good fit.

In 2021 we sold stuff though FOMO, those extreme days are behind us. I'm assuming that sales in future will be based on perceived need. People will have a greater perceived need if they know they enjoy playing the game and they get fairly competent at it. Players also need to develop a playing habit, which will be made easier when the new iOS app arrives. So the aim should be spreading the enjoyment of the game as far and wide as possible. People that play for free will tell their friends and some of them after mastering the game may start buying cards and packs.

This way of growing the game organically could be very powerful and because the entry is a web2 approach it's attracting gamers not P2E types too.

Who are the target groups of players:

1. New players after completing the beginner Campaigns
2. Existing players who have spent all their energy for the day in normal ranked.
3. Existing players who have no time to play right now and have rented out their collection, but they can still play once or twice a week.
4. Existing players who due to personal reasons had to sell their battle cards, but still want to play.
5. Historic players, who sold a while ago but still enjoy the game.
6. Friends of existing players who want a way of sharing the game with them.

All groups could end up eventually spending money on cards and packs because they realise how much they enjoy playing. Playing itself instils a need in people if they enjoy it.

Therefore any name that sounds too beginnery could be missing the mark. At the moment I'm seeing Frontier as the best choice from those listed above
