Infinite mana/counters T3 Win combo #Ashnod's Altar (Legacy)

Hi everyone and welcome! i hope you will enjoy this deck. The deck is based on an infinite combo you can get turn 3 (based on 7 cards in the following best play example) Here is how it works:
turn 1: land + arbor elf
turn 2: land + enchant the other land with utopia sprawl --> tap to add 2 then untap with arbor elf --> you have 4 mana: play rot shambler + animation module or ashnod's Altar + Animation module or algae gharial.
turn 3: you have at least five mana with the arbor elf so you can play the missing part of the combo (althar's ashnod in the first case, rot shambler or algae gharial in the second case and ashnod's altar + animation module if you played algae gharial turn 2). Once you did so you have the combo: sacrifice arbor elf to add 2 to your mana pool, which makes u put a counter on rot shambler/algae gharial, pay 1 for animation module's token (you still have 1 in your mana pool), then sacrifice animation module's token to do the combo again. Rot shambler and/or alga gharial get infinite counters and you have infinite mana to cast emrakul or ulamog.

this is obviously the best play you could get but the combo is just : ashnod's altar + animation module + algae gharial + random creature to do the first sacrifice.

Thanks for reading and don't hesitate to comment if you have any advice!
