Valley Floodcaller + Sensei's Divining Top + Poison Dart Frog + Mm'menon, the Right Hand

Valley Floodcaller

Sensei's Divining Top

Poison Dart Frog

Mm'menon, the Right Hand

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 clever loop relies on Mm'menon, the Right Hand to let you look at the top of your library and cast artifact spells right off the top, while its passive mana-producing ability turns all your artifacts into specialized mana sources. With that foundation set, Poison Dart Frog taps to pay for Sensei's Divining Top, which you then activate to draw a card and place itself back on top of your library for Mm'menon to catch. Casting Sensei's Divining Top triggers Valley Floodcaller, whose static and triggered abilities untap your Frogs and pump them up in the process. Because Valley Floodcaller also grants flash to noncreature spells, everything flows seamlessly into an endless engine of card draw, storm count, and pumped creature stats.
