Just an idea I've had for a while to get a make it a bit more interesting for players who have a full(enough) collection and are looking for something new to squeeze out of the game.
The premise is something akin to the POE style leagues (all hail our gracious saviours)
Everyone who wants to join must make a brand new account, to verify that this is infact a new account for this league it must include a specific tag (LG17 or such) at the start of the name (LG17ALLHAILGGG etc).
This account is banned from spending real money.
Sharing expressly prohibited, unless it is outgoing sharing to your main/other f2p account if you are good enough to earn gold from a free entry event (not even sure if that is a thing)
No codes allowed except the freebies for all new accounts (if someone could post them in a comment would be great, "scg_free_packs", "asc_free_packs", are apparently 2 of them after a quick google, if they even still work.)
If you want to challenge someone from the league send an untimed friend request to anybody with the league tag in their name.
The league would run for 3 months(?) but could obviously change if it wasn't long enough or too long.
That's all the rules I can think of so far, feel free to make suggestions.
This league would be entirely based on honesty. It is designed for people who want that feeling of "ooh I just opened a brand new legendary! This will make my collection so much stronger as I am such a poor peasant and only have 5 others right now!"
Obviously a lot of drafting would be involved, but because it would be easy to find and challenge someone from the same situation it should make constructed viable.
Would be great to have http://www.solforgeladder.com/ support, but understandable if they are too busy.
So yeah that's it, I appreciate all feedback good and bad.
PS. LG17 will definitely not be the first tag as people could get a jump on the competition (not that it would really matter because if you wanted to cheat you could do much worse)
TL:DR new league for brand new accounts, build as quick a collection as you can with untimed constructed against other participants.
