I'll take a random stab at how you win.
1-Do the Dragon Loop w/ Bazaar in play, dump a bunch of your library into grave, make inf. mana.
2-Stop the loop by bringing back Witness
3-Recur another animate spell w/ Witness
4-Play the Animate spell on a Dragon, the loop means you can use Witness to bring something back every turn w/ inf mana, draw everything out of your grave.
5-End the loop by dumping the animate spell on a Squee/Xantid you left.
6-Replay everything you want from your hand and feel free to replay an animate spell and repeat the loop inf. times.
Since a Squee dies from legendary status, everytime you recur more than one, you can put one back to keep stopping and repeating the loop.
7-Eventually just hardcast a WGD and win w/ beatdown from whatever.
All you'd really need to worry about is decking yourself obv.

That correct?
