THIS IS NOT A DECK. Comment, list as many infinite damage combos you can find. You can request a deck based on one of these combos and I'll work on it.
put a wirewood channeler and any elf, put pemmin's aura on it, tap then untap infinite times for infinite blue mana, then tap and untap for infinite red mana, use banfire.
use midcrank with Bloodchief Ascension. you have to have three quest counters and then it works. damage equals discard, discard equals damage, and so on till they die. http://www.mtgvault.com/ViewDeck.aspx?DeckID=187837
enduring renewal on the field, attach deathrender to a mogg fantic, sacrifice mogg fantic, beacuse of enduring renewal it goes into your hand, use deathrenders ability to put it back on the field, repeat till you win. ( instead of mogg fantic if you want you can use anything that you can sacrifice for free damage, thats a creature.)http://www.mtgvault.com/ViewDeck.aspx?DeckID=188644
another is put enduring renewal and mycosynth lattice on the field, attach deathrender to a creature then use ashnod 's altar to sacrifice, enduring renewal with deathrender puts it back on the field, use for infinite colorless and since mycosynth lattice is on the field you can use that mana for banefire. (instead of ashnod's altar you can use anything that says sacrifice, add mana to your mana pool).
intruder alarm, sliver queen, 2 gemhide sliver. tap gemhide slivers for two mana, use that on sliver queens effect, because of intruder alarm the sliver untaps the gemhides. repeat. (if you want to win the same turn use heart sliver.) http://www.mtgvault.com/ViewDeck.aspx?DeckID=187817
xenograft and turntimber ranger. choose ally, put a creature on the field, it's an ally because of xenograft so you get a wolf, thats an ally, so you get another, and it keeps going so you get infinite wolfs.

put mycosynth lattice, march of the machines, chandra nalaar, and quicksilver elemental on the field. mycosynth makes chandra an artifact, march makes chandra a creature, then quicksilver copies it's abilities and since the one per turn only applies to plansewalkers you spam 1 damage infinite times.
