Overview

Circle of Dreams Druid’s {T}

ability produces {G}

equal to the number of creatures you control. Staff of Domination has a {3}

activated ability that can untap a target creature and a separate {1}

activated ability that untaps the Staff itself. By tapping the Druid for mana, using Staff’s {3}

to untap the Druid, then paying {1}

to untap the Staff, you create a loop whose net mana per cycle = (number of creatures you control) − 4. If you control five or more creatures, that loop generates infinite green mana. Note that the Druid can only activate its {T}

ability if it’s been under your control continuously since the turn began (summoning sickness) .

Step 1

Ensure the Druid has been under your control continuously since your most recent turn began (it can’t activate its {T}

ability if it has summoning sickness) .

Step 2

Activate Circle of Dreams Druid’s ability by paying its {T}

cost: tap the Druid. When that ability resolves, it adds {G}

equal to the number of creatures you control (call that number n).

Step 3

Pay

of the mana you just produced (or other available mana) and activate Staff of Domination’s {3}

: Untap target creature, tapping the Staff as part of that cost. Target the Circle of Dreams Druid with that ability; when it resolves the Druid becomes untapped.

Step 4

Activate Staff’s {1}

: Untap this artifact by paying {1}

(this ability has no tap symbol and therefore can be activated while the Staff is tapped). When that resolves the Staff becomes untapped.

Step 5

You are back to the starting position except you have spent {4}

total mana and gained n mana from the Druid’s tap. Net mana change = n − 4. If n ≥ 5 each loop produces net positive mana; repeat to generate arbitrarily large amounts of green mana.

Resolution

Core ruling: Tap Circle of Dreams Druid to add {G}

equal to the number of creatures you control. Pay {3}

and tap Staff of Domination to activate its {3}

: Untap target creature, targeting the Druid. Then pay {1}

to activate Staff’s {1}

: Untap this artifact. Repeat. Each repetition nets (creatures you control) − 4 mana, so with five or more creatures you get a positive net mana per repetition and can produce infinite green mana. The Druid’s tap ability cannot be activated if it has summoning sickness (it must have been under your control continuously since your most recent turn began) . Also remember that tapping/untapping used here are activation costs (they are paid as part of activating abilities) .
