Isochron Scepter + Nimbleclaw Adept + Flicker of Fate + Anger

Isochron Scepter

Nimbleclaw Adept

Flicker of Fate

Anger

How it works

1. Activate a mana-producing permanent by tapping it, adding at least 2.
2. Activate Nimbleclaw Adept by tapping it, untapping Isochron Scepter and the mana-producing permanent.
3. Activate Isochron Scepter by paying 2 and tapping it, casting a copy of Flicker of Fate without paying its mana cost.
4. Resolve Flicker of Fate, blinking Nimbleclaw Adept.
5. Repeat.

This elegant loop relies on untapping mechanics to continuously recast a single spell using Isochron Scepter. By imprinting Flicker of Fate onto the Scepter, you gain access to a repeatable blink effect. Nimbleclaw Adept is the engine of the operation, since its tap ability untaps both the Scepter and whatever mana source is footing the activation cost. Whenever the Adept's Bigby's Hand ability blinks the Adept itself via Flicker of Fate, it returns to the battlefield fresh and ready to untap everything all over again. Meanwhile, having Anger in your graveyard provides a nice passive bonus—giving all your creatures haste as long as you control a Mountain, ensuring everything is fully operational the moment it hits the board.
