Bravo, you’ve found yet another example of how these so-called ‘deck trackers’ are used for cheating, and with an illustration at that.
Still, they’re gonna keep denying it and see no evil. For example: Friend requests from fighting pit and so on.
Roughly the same as the one that a player using a ‘map hack’ in Warcraft 3 or a ‘wall hack’ in a shooter has.
In other words, if the opponent cheats too (uses a ‘deck tracker’, map/wall hack etc), there is no advantage.
Something’s not right to me in this reasoning. Maybe the assumption that cheating is normal in the first place?
PS Oh, wait, there’s an even better one. Imagine I can see the cards in your hand as we play against each other. Where’s my advantage, I ask you? You can see those cards too. 
Nope. That’s more of a mental crutch for those who lack the capacity to perform even such a trifling task or are outright lazy.
A wheelchair surely does provide an advantage, but mostly to those who can’t just walk for some reason.
If ‘deck trackers’ were just those without ‘extras’, such as revealing cards in the opponent’s hand, there’d be very little reason to use them.
PS Forgot to add: I understand why streamers might want to use them, so that any viewer can see what’s in the deck etc at any time — but that’s a slightly different story.
Bingo.
At least someone’s not denying it.
By the way, it’s the game that should be fixed in such cases.
Wait, for once you aren’t defending the game with its flaws even in the face of overwhelming evidence? 
I don’t recognise you.
And that’s the whole point here.
