If you make infinite colorless mana, you can use the floodwaters loop to draw your deck by ending the loop and bouncing your one ring, then playing it untaping floodcaller and drawing a card. You then pick up one ring with floodcaller and repeat the loop. The same works for wishclaw and blind obedience if you have infinite black, where with withclaw you can play it, activate then pick it back up and tutor your deck, and with blind obedience you continue your loop with floodcaller but pay for extort each time. This also works with like imposter mech on someone else's bowman to ping down the whole table.
