Iron Lad, Diverging Destiny

The engine here is only as good as your intelligence about what comes next, and the passive peek is the piece that supplies it. Read the tap in isolation and it is a coin flip: reveal, hope for an artifact, draw or brick. Add the standing permission to look before you commit, and the reveal stops being a gamble and becomes a scheduled draw, tapped only in the turns when you already know an artifact is sitting there waiting. That turns the whole card into a variance-free version of an effect that is usually all variance, at the price of a build that keeps artifacts dense enough for the surface to stay cooperative. The 2/2 with flying and vigilance earns its keep while the engine idles: it can attack for value without shutting off the tap ability, so pressuring life totals and grinding cards happen in the same combat step rather than competing for the turn. This is a slow, grinding artifact payoff, not an explosive one, and it does nothing in a deck that cannot feed it. It sits in the long line of blue card-selection pieces that ask you to commit to an archetype before they earn their slot, trading raw ceiling for repeatability and, unusually, stripping out the randomness those top-deck-reveal effects normally carry.
