Valley Floodcaller + Sensei's Divining Top + Poison Dart Frog + One with the Multiverse

Valley Floodcaller

Sensei's Divining Top

Poison Dart Frog

One with the Multiverse

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 centers around One with the Multiverse, which grants you the crucial ability to cast spells directly from the top of your library. With Sensei's Divining Top sitting neatly on top, you can tap it to draw a card and slide itself right back into that library-top position, where One with the Multiverse lets you cast it again for just one mana. To fund this recurring cost, Poison Dart Frog steps in as your dedicated mana producer, tapping to generate the single mana needed to replay the Top. Meanwhile, Valley Floodcaller watches every artifact spell you cast and untaps your Frogs in response, ensuring Poison Dart Frog is ready to tap for mana again and again while simultaneously pumping your board to massive proportions.
