Omnistone. Draft not random?

Suggestion for improving omnistone. Allow the player to choose 1-3 runes that cannot appear. Those runes won't appear for the rest of the game. Keep it otherwise working the same as live.

I think on most champions, it's the "dead" runes that keep them from even meme consideration of omnistone.

This would require a custom UI, like with Unsealed Spellbook. However, the UI window would only need to be active once at the start of the game. It's even plausible to have the UI on a timer (must decide before X mins into the game).

The idea behind this suggestion is that the _inverse of unsealed spellbook may work better (decide what you do not want) rather then the usual suggestion of "choose your next rune".

Omnistone may be better thought in terms of card game drafting. Too many "bad" results in a deck makes the deck a lot worse. Thinning decks of their worst cards is often one of the strongest moves in drafting card games. Let us thin the omnistone deck and the increased consistency is the best way to maintain randomness while keeping it reliable.
