I mean what's the point in doing a tournament if it's not even based over skill but luck? The TT tournament with plus rule is fine and show who can make his way by thinking faster than the other. But the tournament with the exchange rule? basically since you are still not able to break the 4* card limit we all end up with 4 card 3* that has 2 sides of 8 value because that the only ones that can't be taken except by the only 4* or 5* your opponent has and that can easily beat an opponent just a bit weaker than you. So what happen when the exchange rule just take your only 4* / 5* card and give you one of you opponent's 3* card? Well you can just watch as your card are useless and he just win without even thinking. At this point you can just hope that either you get your opponent strongest card, or the exchange just exchange cards of the same rank. But honestly there's no fun in playing in a tournament when you know your place will be randomly chose by the game's RNG.
