Kind of bi-polar, nice and mean. This was made in haste with what was primarily ON HAND at the time. There are definitely poor things in here, and some sub-optimal choices.

Notable/Non-obvious infinite combos:

If it's on board and you haven't made infinite anything, something weird is happening. It's innocous, and easily fetchable with Trinket Mage, Fabricate and Reshape.

Play Magosi (untapped thanks to Amulet) and put a counter on it. Untap with Frantic Search, or cast Time Stretch. Use Rings to double the extra turn. By spending 1 turn you get 2 turns thus having infinite turns.

By using most of the Sorotami's "return land" abilities, you can place them, and return them again, netting infinite mana to give someone a Stroke (of Genius).
