Use this before the big storm turn. Count mana, draw, damage, and Aetherflux life before committing resources.
Count Veyran outputs before you start storming.
Estimate Treasures, cards, damage, tokens, Aetherflux life, Birgi mana, and Veyran pump from casts and copies.
Estimated trigger output
Storm-Kiln is a Dwarf Wizard and triggers from casts/copies; Veyran and Harmonic Prodigy can each add one trigger.
Archmage is a Wizard with magecraft. Casts and copies both trigger it.
Guttersnipe is a Goblin Shaman. Harmonic applies; each trigger deals 2.
Birgi triggers on casts only. Harmonic Prodigy does not apply to Birgi.
Veyran is a Wizard, so Harmonic can add one more pump trigger. Temporary until end of turn.
Rules note: Veyran doubles permanent triggers caused by casting/copying instants or sorceries. She does not double storm itself.
Exact line calculators
These are quick math checks for the most common mistake-prone Veyran lines.
Isochron + Dramatic
At 2 mana it creates infinite triggers if you have a payoff. At 3+ it creates infinite mana.
Reiterate + Mana Geyser
Reiterate with buyback costs 6 total. You want Mana Geyser producing 7+ to net mana.
Aetherflux storm turn
Normal Reservoir math: 28 life. Veyran can add extra triggers for instant/sorcery casts; copies usually do not count as casts.
After checking the math
Paste your list into the Deck Auditor to see whether your build has the engine density to execute the turn.
