Oh, there are plenty of ways to go infinite in Magic. I've done it once or twice with Nekusar; Mind Over Matter and Temple Bell on turn 6 is devastating.
Made a blue/green inifinte mana loop with a bunch of nasty stuff to spend that mana on, It could go infinite damage, infinite mill, summon all my (out of game) eldrazi at once or go for that stupid "put 100 tokens on this enchantment to win" card. Then I threw in Phyrexian hydra + distortion strike, so i could win by poison counters aswel.
And then I hear tell that yugioh is even worse.
