Fblthp, Impossibly Lost — ruling 1

Losing the game due to drawing from an empty library happens as a state-based action. At certain times (usually after each spell and ability resolves) the game checks to see if any state-based actions need to be performed, then does so. Since Fblthp's ability causes you to win the game while that ability is still resolving, this happens before those state-based actions would be checked and performed. Notably, drawing cards from an empty library at any other time while Fblthp is on the battlefield will still cause you to lose the game.

Fblthp, Impossibly Lost : règles, fonctionnement et interactions (MTG)

Fblthp, Impossibly Lost 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.

Official card text

When one or more of your opponents are dealt combat damage during your turn, draw two cards. If your library has no cards in it, you win the game. Fblthp's owner shuffles him into their library. (If you draw from an empty library this way, you still win the game.)

Complete guide

Fblthp, Impossibly Lost offers a unique twist on the classic 'Laboratory Maniac' effect, rewarding you for successful attacks. While he usually hides away in your library, his presence turns a potential loss from an empty deck into an immediate victory. Let's explore how this Homunculus turns your combat damage into a game-winning draw.

Winning the Game

Fblthp's ability triggers whenever one or more of your opponents are dealt combat damage during your turn. When this resolves, you draw two cards. If your library is empty, the ability checks this state immediately. Instead of waiting for state-based actions that usually cause a loss for drawing from an empty library, Fblthp intervenes and grants you the win right then and there.

The Shuffle Clause

After checking for the win condition, Fblthp's ability instructs his owner to shuffle him into their library. This is a mandatory part of the resolution. If you won the game, this part technically happens but doesn't matter; however, if you didn't win, Fblthp will leave the battlefield and become a hidden card in your deck once more.

Timing and State-Based Actions

A common mistake is thinking Fblthp protects you from losing to an empty library at all times. He does not. He only prevents the loss and grants a win during the resolution of his specific triggered ability. If you are forced to draw from an empty library via another spell or your draw step while Fblthp is simply sitting on the battlefield, you will still lose the game.

Interaction examples

Combat Connection

Ornithopter of Paradise

You have Fblthp, Impossibly Lost and Ornithopter of Paradise on the battlefield. You attack your opponent with Ornithopter of Paradise, and it deals 1 combat damage. Fblthp's ability triggers. When it resolves, you draw two cards. If those were the last two cards in your deck, you are safe for now, but Fblthp shuffles himself back into your library.

The Empty Library Win

Foundry Inspector

Your library has zero cards left. You attack an opponent with Foundry Inspector and Fblthp. If Foundry Inspector deals combat damage, Fblthp's ability triggers. As it resolves, the game sees you need to draw from an empty library. Before state-based actions check if you've lost, Fblthp's effect sees the empty library and you win the game immediately.
