I like the "limited contact" play style of R4tG, however what most people ignore is that there is at least 1 method of hindering your opponent: Card denial

If you see an opponent is playing a certain strategy, and a card that would help them comes into your hand, you can “hold it” or play it yourself to prevent them from getting it. There is a calculated risk in tying up your own resources to deny them a card, but there are times when it will make a difference.
