Valley Floodcaller + Sensei's Divining Top + Birds of Paradise + Experimental Frenzy

Valley Floodcaller

Sensei's Divining Top

Birds of Paradise

Experimental Frenzy

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 clever loop turns the top of your library into an engine for endless card draw, powered by the synergy between Experimental Frenzy and Sensei's Divining Top. With Experimental Frenzy letting you cast spells directly from your library, you can repeatedly tap Sensei's Divining Top to draw a card and place itself back on top, only to immediately recast it. Meanwhile, Valley Floodcaller grants you the vital untap trigger whenever you cast that artifact, allowing you to continually ready your mana source. Tapping Birds of Paradise provides the exact mana needed to pay for Sensei's Divining Top's casting cost, sealing a self-sustaining cycle that also pumps your qualified creature types to towering proportions.
