Valley Floodcaller + Sensei's Divining Top + Poison Dart Frog + The Reality Chip

Valley Floodcaller

Sensei's Divining Top

Poison Dart Frog

The Reality Chip

How it works

1. Activate Poison Dart Frog's first ability by tapping it, adding 1.
2. Activate Sensei's Divining Top's second ability by tapping it, causing you to draw a card and put Sensei's Divining Top from the battlefield onto the top of your library.
3. Cast Sensei's Divining Top from the top of your library by paying 1.
4. Valley Floodcaller triggers, giving Birds, Otters, Frogs and Rats you control +1/+1 until end of turn and untapping them.
5. Repeat.

This elegant loop lets you draw your entire deck by repeatedly cycling Sensei's Divining Top right off the top of your library. The Reality Chip makes this possible by granting you the crucial ability to cast spells directly from the top, while Poison Dart Frog provides the exact amount of mana needed to pay for the artifact's upkeep cost each time. Meanwhile, Valley Floodcaller acts as the engine's heartbeat, turning every cast of Sensei's Divining Top into a free untap for your Poison Dart Frog so the mana can flow uninterrupted.
