Overview

Priest of Titania’s tap ability produces {G}

for each Elf on the battlefield (including itself and opponents’ Elves) . You can use that mana to pay Staff of Domination’s activated abilities — notably {3}

: Untap target creature and {1}

: Untap this artifact — to untap Priest and then untap the Staff, returning both to their original untapped state so you can repeat the sequence. The Priest’s tap ability can be activated repeatedly during your turn only if the Priest has been under your control continuously since your most recent turn began .

Step 1

Ensure Priest of Titania has been under your control continuously since the start of your most recent turn so you may activate its {T}

-ability .

Step 2

Activate Priest of Titania’s ability: tap it to add {G}

equal to the number of Elves on the battlefield (call that number N) .

Step 3

Use

of that mana to activate Staff of Domination’s {3}

: Untap target creature ability, tapping the Staff as part of that activation and targeting the Priest .

Step 4

When that ability resolves, the Priest becomes untapped (Staff remains tapped).

Step 5

Activate Staff of Domination’s {1}

: Untap this artifact ability, paying {1}

to untap the Staff.

Step 6

After steps above both Priest and Staff are untapped and you have spent a total of 4 mana from the Priest’s tap; you have returned to the same physical/tap state as before the sequence and may repeat the sequence by tapping Priest again .

Step 7

Evaluate N: if N > 4 each repetition yields net (N - 4) green mana (infinite mana by repeating); if N = 4 you can repeat indefinitely but with no net mana gain; if N < 4 you cannot complete the 2-step untap cycle from a single Priest tap because you don’t have enough mana to both pay {3}

and

Resolution

Basic loop: Tap Priest of Titania to add N {G}

(N = number of Elves) . Pay {3}

and tap Staff of Domination to activate its {3}

: Untap target creature, targeting the Priest; that will untap the Priest. Then pay {1}

to activate Staff’s {1}

: Untap this artifact to untap the Staff. After those two activations both Priest and Staff are untapped and you’ve spent 4 mana from the Priest’s tap. If N > 4 you gain net mana each cycle (infinite green mana over repeated cycles); if N = 4 you can repeat the cycle indefinitely but without net mana gain; if N < 4 you cannot complete the cycle because you can’t both untap the Priest and untap the Staff from a single Priest tap. The Priest’s tap ability can only be activated if it has been under your control continuously since the start of your most recent turn , and Priest’s mana amount is counted as all Elves on the battlefield (including itself and opponents’ Elves) .
