Magic has been going for the better part of 30 years and in that time it can released thousands of cards. Sometimes, two or three or even more cards can be used in tandem to create infinite effects, ones which trigger off one another to obtain game-breaking results.
While the designers certainly try to eliminate cards which are too powerful in conjunction with one-another within the same set, through the sheer amount of cards in the game as a whole, it would be impossible to eliminate all of them. Sometimes effects are too powerful and a card might need to be banned here and there for the good of the game, but if Wizards of the Coast got rid of every card that could cause an infinite combo, they'd surely lose a decent percentage of their entire card-base.
This is a list of what we deem to be the top-ten game-breaking effects, measured through power, effectiveness, and how easy it is to pull off. Before you try these in your matches, keep in mind that some of these might be exclusive to certain formats as ban lists are fairly regularly updated.
So strap yourselves in as we explore some of the most insane infinite combos in the Magic the Gathering.
