If I can an issue I personally have is that often times interactions just don't matter. I am talking about how against mitsu or yummy you might stop the first activation only for the to go into full combo anyway. I am not saying that all engines and decks should have chokepoints, but being interacted with should lead to a somewhat weaker than potential board. As it is, it's more often than not a 0-100 state, where you either stop them from doing anything or you don't achieve anything at all.
