My arguments may have seemed over exaggerated to you but they hold true. The best are the best for a reason.
I'm afraid that you're incorrect yet again - here's why.
All of your examples are of people who are #1 due to personal skill.
While there is some skill in knowing what the max level and abilities of a given card are and rearranging your card order to take advantage of this, that only comes into play with two relatively evenly matched decks - in the end this game ultimately comes down to who has earned/bought the best deck.
Take the best player in the game and give him a deck of non-silver 3* cards and have him face off against someone who's never heard of this game before but has a deck of gold 6* cards - who's gonna win?
Your examples are all of people playing games where you're the best because of speed, agility and knowledge of the game - your fighting game champion was not the best because he went out and bought a $1000 joystick, he was the best because of speed, impeccable timing of attacks and blocks and the ability to recite every combo move in the game backwards in his sleep.
If your champion and I both put a quarter into MvC at the arcade and take the exact same characters it will come down to skill as to who wins - probably him as Dark Stalkers was my fighting game of choice.
But if he starts playing PM today and tries to brawl me at level 3 I'm going to wipe the floor with him, not because I can hit the brawl button faster or know the stats of every card by heart, but because I've played far longer and my deck is three times stronger then his.
Of course, if you had ever participated in or followed video games on a professional or tournament level you would know the difference between someone winning because they were more skilled and someone winning because they had a 40 level advantage on their opponent.
