Elite draft tokens.
Would be cool if scoring 7 wins in a premium draft would be rewarded with "elite draft tokens". Say you'd get 3 minus number of losses 1-3. These could be used to enter "Elite drafts" - that can only be entered with those tokens - not by gold or gems. These would always be phantom drafts and haw small prizes - but have as first prices qualifier play in points.
The purpose would be to have drafts where there's only skilled - or lucky players.. And since they would be essentially free there would not be a much negative incentive to enter because of tougher opponents. Streamers and audiences would probably love these.
Prices could include "trophy cosmetics" - avatars, sleeves, stickers, companions ... that can only be obtained through the elite events.
