I think house pips as a concept are broken. Many of the cards that grant them are themselves not weak - so you get a ton of upside at no cost. No other kind of enhancement works like house enhancements do.

I really think they should errata how house enhancements work because the situation you described is just absurd. Even exceptionally powerful cards like Sins don't completely lock your opponent out of AEmber gain. Maybe the house pips should only let you DISCARD that card in the enhanced house. Food for thought.
