Kefnet's Monument + Tangleroot + Dream Stalker + Mycosynth Lattice

Kefnet's Monument

Tangleroot

Dream Stalker

Mycosynth Lattice

How it works

1. Cast Dream Stalker by paying 1.
2. Kefnet's Monument and Tangleroot triggers.
3. Resolve the Kefnet's Monument trigger, tapping target creature an opponent controls.
4. Resolve the Tangleroot trigger, adding 1.
5. Dream Stalker enters the battlefield, returning it to your hand.
6. Repeat.

This charming little loop turns Dream Stalker into a self-returning engine by leveraging Mycosynth Lattice, which conveniently transforms everything into an artifact so you can loop your creature with its own triggered ability. As you repeatedly cast the Stalker for just one mana, Kefnet's Monument graciously absorbs that cost reduction while simultaneously locking down your opponents' creatures. Meanwhile, Tangleroot happily refunds that mana on every single casting, fueling the whole continuous cycle into an infinite storm count and endless enters-the-battlefield triggers.
