Battlefield
Artifacts already here do not trigger Fateful Discovery when the enchantment resolves.
Whenever an artifact you control enters, draw a card.
Assumes you paid {3}{U}{U}, including two blue mana. Resolving it spends the card in hand and draws zero cards.Record a resolved token-making effect. Each token enters separately for trigger counting, even when they enter simultaneously.
Records one completed bounce/recast or blink sequence. Its enablers and costs must be supplied by your deck; this is not a free combo.
Interaction & recovery
Removing a permanent does not undo cards already drawn or remove its triggers already on the stack. An artifact-only wipe leaves this enchantment in play; an effect that also removes enchantments does not.
An engine for future entries
Five artifacts in play → resolve Fateful Discovery → draw zero. Then create three Treasures → three draw triggers. Resolve them → draw three. Sacrificing those Treasures later does not undo those draws.
For Commander, evaluate this as a persistent engine and potential combo piece: artifact-token production, cheap artifacts, and repeatable re-entry can keep generating draws. A repeatable loop still needs its own enablers, resources, and a way to win. The draw is mandatory, so running out of library can make you lose.
A one-shot payoff for an established board asks a different question. The community’s Edgar, King of Figaro and Armor Wars comparisons belong to that discussion; they are not this enchantment’s draw rule. Thoughtcast-style immediate refills likewise do not measure the same role.
The old version incorrectly treated Fateful Discovery as a one-shot draw equal to the artifact count. This version tracks actual entries, pending triggers, and resolved draws instead. Casting the enchantment normally uses sorcery timing; its artifact-entry ability can trigger on any player’s turn.
