I am so tired of this bullcrap that you can play gazillion of cards in a turn! Can you please stop this nonsense and make it so that you would actually had to be THINKING about what your next turn will be instead of just volmittin 20 cards with NO COST whatsosoever, its sof****ng frustrating!
Give an example of a 0 cost card that you never have to think about it.
yasss nerf desk imp n snowflipper penguin they too OP 
You’re choosing to be obtuse, no one cares if a weak minion with no effect is 0, but a high powered spell or monster shouldn’t cost 0 ever. Maybe 1, but never 0 imo
There’s also Shadowstep, which under certain contexts it’s the most powerful card in the game by far.
The problem with the OP is not that; their argument is “they don’t need any thinking”; yeah right.
