...Imagine if you could play cards/make decisions during your opponents turn, or in response to them playing a card. Not having that is the oddest thing about Hearthstone.
Yugioh, for example, has trap cards. Which you put down beforehand, and can choose to activate during the opponents turn in response to what they do. There are more things you can do, like Quick Play Spells and Handtraps, but Trap Cards are well known and relatively simple.
Hearthstone ONLY has secrets, which you can play preemptively, but them triggering is always a triggered thing, not something you can choose to do.
