What must be in place

How to execute it

  1. Animate Brass Infiniscope.
  2. Activate Brass Infiniscope by tapping it, adding {C}{C} and creating a delayed triggered ability.
  3. Activate Voltaic Construct by paying {2}, untapping Brass Infiniscope.
  4. Repeat steps 2 and 3 as desired.
  5. Cast the spell with {X} in its mana cost, with {X} being at least 2 if you wish to gain life.
  6. Each instance of Brass Infiniscope's delayed triggered ability triggers, causing you to draw a card and gain half X life, rounded down, for each trigger.
