Basalt Monolith + Forsaken Monument

Overview

When you tap Basalt Monolith for its {T}

: Add

ability while you control Forsaken Monument, Basalt Monolith produces three colorless mana and Forsaken Monument’s ability adds one additional {C}

, for a total of four colorless. Forsaken Monument’s extra-mana ability applies only once per permanent tapped even if that permanent produced more than one {C}

[Ruling [2020-09-25]]. Basalt Monolith’s {3}

: Untap this artifact ability can be paid repeatedly using mana you made this way, letting you repeat the sequence and generate a net +1 colorless each loop (so you can make infinite mana if Monolith is untapped to start or you can initially pay to untap it) [Ruling [2020-08-07]].

Step 1

Have Basalt Monolith and Forsaken Monument on the battlefield under your control, and have Basalt Monolith untapped (or be able to pay {3}

to untap it to start).

Step 2

Activate Basalt Monolith’s {T}

: Add

. That tap event produces three colorless mana from the Monolith.

Step 3

Forsaken Monument’s triggered ability sees that you tapped a permanent and that the tap produced colorless mana, so it triggers and will add one additional {C}

when it resolves (Monument adds only one {C}

for that tap even though the Monolith produced three) [Ruling [2020-09-25]].

Step 4

You now have {C}

available (three from Monolith, one from Monument).

Step 5

Pay

to activate Basalt Monolith’s {3}

: Untap this artifact ability. Use three of the four colorless you just generated to pay that cost.

Step 6

Basalt Monolith becomes untapped. You have one colorless left over from the cycle, so the net result of the cycle is + {C}

Step 7

Repeat: tap Basalt Monolith again for {C}

, Monument adds one {C}

, pay

to untap, netting {C}

each loop. Because Basalt Monolith’s untap ability can be paid repeatedly, the loop can be repeated as long as you can pay the untap cost each time, yielding an unbounded amount of colorless mana if you can start the loop [Ruling [2020-08-07]].

Resolution

Tap Basalt Monolith: you get {C}

. Forsaken Monument triggers once for that tap and adds {C}

, so you receive {C}

total [Ruling [2020-09-25]]. You may pay {3}

to untap Basalt Monolith with its ability and repeat the process; each full cycle (tap for 3 → Monument adds 1 → pay 3 to untap) nets you {C}

and can be repeated as often as you can pay for the untap cost, allowing an unbounded result if you can start the loop (Basalt Monolith’s untap ability can be used repeatedly) [Ruling [2020-08-07]].
