And those changes will break balance of some Leshii decks (and who knows what else) while need just to fix only one type. Boosting immune cards in hand is not real glitch, cause by game mechanics as target counts only cards that laying on table, not in deck or graveyard, as i understand. And as i can guess it was planned so, to make different mechanics, not just another buff.It is super annoying, but I think your proposed solution would be a bit over the top. Just making "no-unit" decks less attractive, by adjusting some current issues (like woodland boosting immune unit on hand) would go a far way in discouraging people to use these kind of decks. I don't think banishing such decks is necessary. Just remove incentives and "glitches".
