Still looking for that perfect New Year’s resolution?

How about this one: Solve a fresh new Magic puzzle from Possibility Storm right here on ChannelFireball every Monday. (There might even be the occasional prize opportunity in it for you—like there is this week!)

This week, the Possibility Storm team wants to see just how much Channel you can pump into a Fireball. Submit your solution at the link below by midnight tomorrow and find out later this week if you’ve won!

Come back each Monday for a new challenge, leave your best attempt in the comments, and come back on Wednesday to see the official solution.

Clever, clever—this winning line submitted by Justin Francis found a way to deal the most damage (2,363) without using Fireball at all!

Either way, all strong lines used the same general approach:

  • Cast High Tide twice.
  • Replace all colorless mana costs with life paid via Channel.
  • Maximize the number of spells cast.
  • Loop Man-o’-War with itself for as long as your blue mana supply will let you.
  • Extract a tiny bit of extra damage by casting instants while Aetherflux Reservoir triggers are still on the stack, since the amount gained is equal to the spells cast as the trigger resolves. (Tricky!)

Without further ado, here’s Justin’s winning line:

    1. Cast High Tide, resolve it.
      Storm count: 1
      Lands untapped: Breeding Pool [4] Steam Vents untapped [3]
      Life: 1 + Aetherflux trigger (1) = 2
    2. Cast Channel, resolve it.
      Storm count: 2
      Lands untapped: Breeding Pool [2] Steam Vents untapped [3]
      Floating blue mana: 2
      Life: 2 + Aetherflux trigger (2) = 4
    3. Cast Walking Ballista for X=1, don’t resolve it.
      Life: 4 – 2 (mana from Channel) = 2
      Storm count: 3
      Lands untapped: Breeding Pool [2] Steam Vents untapped [3]
      Floating blue mana: 2
