I got an idea
What if you can use 3 of the same skin/champ shard and turn them into a permanent. Would be fair to get champs since people want to get champs for free faster, and for skins cause some people might have a huge supply of extra shards, and riot would want you to spend more money on chests to get the exact 3 shards. Might be dumb, but I like it.
My other idea was Emoji Amumu, but that's a stupid idea.
