Valley Floodcaller + Sensei's Divining Top + Birds of Paradise + Future Sight

Valley Floodcaller

Sensei's Divining Top

Birds of Paradise

Future Sight

How it works

1. Activate Birds of Paradise 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 ingenious loop turns Sensei's Divining Top into a self-sustaining engine by repeatedly drawing the artifact and casting it directly from the top of your library, a feat made possible because Future Sight lets you play spells from the very top of your deck. To keep the mana flowing for this recurring cast, Birds of Paradise provides the necessary funds each iteration by tapping for {1}. Meanwhile, Valley Floodcaller acts as the mechanical heart of the combination, ensuring that whenever you cast the noncreature Top, its triggered ability untaps your Birds of Paradise so they can produce mana again while also growing your specific creature types into an overwhelming force.
