Saheeli, Sublime Artificer + Mirror of Fate + Contagion Engine + Part the Waterveil

Saheeli, Sublime Artificer

Mirror of Fate

Contagion Engine

Part the Waterveil

How it works

1. Cast Part the Waterveil by paying 4.
2. Saheeli triggers, creating a 1/1 Servo artifact creature token.
3. Resolve Part the Waterveil, causing you to take an extra turn after this one and exile it.
4. Activate Contagion Engine by paying 6 and tapping it, putting two loyalty counters on Saheeli.
5. Activate Saheeli by removing two loyalty counters from it, causing the Servo to become a copy of Mirror of Fate until end of turn.
6. Activate the Servo by tapping and sacrificing it, choosing Part the Waterveil and up to six other cards face up in exile, then exiling your library and putting the chosen cards on top of your library, with Part the Waterveil being the top most card.
7. Move to your next turn, drawing Part the Waterveil during your draw step.
8. Repeat.
