I mean... sometimes I play against someone that made a very cool deck! Or made a certain twist to a meta deck and won, so I want to see what they decided to sacrifice in the meta deck for example...!

I shouldn't be the one justifying, you should be the one providing a solid reason to why it should NOT be added, and simply "would make me be less creative" is not a good reason, and again I repeat, most opponents see most of your deck and your main strategy, so what are you trying to hide? If you didn't play your "important cards" like you said then why would anyone want to import your deck if they didn't see your important cards??

With all do respect, your comment makes no sense to me, like at all! All I'm seeing is disagreement for the sake of disagreement...
