Vance's Blasting Cannons // Spitfire Bastion is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.

Complete guide
Vance's Blasting Cannons is a powerful legendary enchantment from Ixalan that provides card advantage through impulsive draw. If you can string together multiple spells in a single turn, it transforms into Spitfire Bastion, a land capable of picking off creatures or finishing opponents.
Impulsive Draw Mechanics
At the beginning of your upkeep, the first ability triggers, exiling the top card of your library. If that card is a nonland card, you gain the ability to cast it for the rest of the turn. You must still pay all mana costs and follow timing restrictions, meaning you cannot cast a creature or sorcery during your upkeep. If the card is a land, you cannot play it, and it remains in exile indefinitely.
The Transformation Process
The second ability tracks how many spells you have cast during the current turn. When you cast your third spell, the ability triggers and goes on the stack on top of that third spell. This means Vance's Blasting Cannons will transform into Spitfire Bastion before the third spell actually resolves. It is important to note that the enchantment must be on the battlefield when the third spell is cast to see that event happen.
Managing Your Spitfire Bastion
Once transformed, Spitfire Bastion is a Legendary Land. It can tap for Red mana, or you can spend three mana and tap it to deal 3 damage to any target. Unlike the enchantment side, the land side does not exile cards from your library during your upkeep, so choose the timing of your transformation carefully if you still need the extra card flow.
Interaction examples
During your upkeep, the Blasting Cannons trigger exiles Shared Animosity. Since Shared Animosity is a nonland card, you may cast it later in the turn during your main phase by paying its mana cost. If you do not cast it by the end of the turn, it remains in exile.
If you have already cast two spells this turn, casting Aggravated Assault will trigger the Blasting Cannons' transformation ability. The ability resolves first, turning the enchantment into Spitfire Bastion. Then, Aggravated Assault resolves and enters the battlefield.
When playing in a tournament, you may use the Ixalan Checklist to represent Vance's Blasting Cannons in your deck to ensure your deck sleeves remain opaque. You must have the actual double-faced card available to swap in whenever the card is on the battlefield or in a visible zone.
