Ban ALL infinite combos. Theyre virtually impossible to counter once they start. They undermine the integrity of the gameplay by completely changing the rules of the win scenario.

Using an infinite combo is like a spoiled rotten brat youre forced to play with as a kid because your mom is worried because they have no friends.
The Brat triumphantly yells, "I Win!" You ask for logic or reasoning and their response is, "just cuz!"

And you wonder why you dont have any friends. Winning with an infinite combo is a cop-out for somebody who cant see the game thru to the end.

Well dear user of infinite combos: You crow and cheer yoursel; prausing the accomplishment of a win that should never have been a possibility in the 1st place. Youre like a guy who brings a gun to a fist fight and upon killing the hulking mass of combat experienced muscle you lawd yourself as the better fighter just because you won (when in reality you are not the better fighter.)

A stronger fighter (i.e. the best players) should look for a challenge to win, not take the easy way out.

WotC used to monitor these things. They used to care about balancing the game and banning infinite combos, but since they abandoned us its up to us, the strong players, to fight for a truly balanced battle.

Dont used infinite combos, dont use cards that change the rules for winning (i.e. you win the if... scenarios), dont use planeswalkers, dont copy other people's deck list, and especially dont use cards that you know are broken. Dont accept the fact that WotC allows these cards. Fight for balance then it comes down to wit, intellect, strategy, cunning, not money and lazy copying.
