I would say harmful: easier to get the broken combos going.
See, I call that a lack of perspective. The only thing you mention is that it would make something that is already avialable easier. But, from what I've seen, those broken combos usually have no problems in setting themselves up without any houserules. However, what else it does is enables lesser class of decks which is extremely questionable or even unplayable otherwise, the point you entirely miss for some reason.
I should have checked the author of the post. I will not make this mistake again. Why even ask mr never miss anything?
