Laughing Jasper Flint

Outlaw is not a creature type. If an effect asks you to choose a creature type, you can’t choose outlaw.

A card, spell, or permanent is an outlaw if it has the Assassin, Mercenary, Pirate, Rogue, or Warlock creature type. It doesn’t matter if it has more than one of those creature types; as long as it has at least one, it’s an outlaw.

Laughing Jasper Flint’s first ability applies to creatures you control but don’t own as they enter the battlefield. For example, if you control Laughing Jasper Flint and Vial Smasher, Gleeful Grenadier, having a creature an opponent owns that normally isn’t an outlaw enter the battlefield under your control will cause Vial Smasher’s ability to trigger.

The value of X is determined as Laughing Jasper Flint’s last ability resolves.

If an ability refers to an outlaw or whether a player controls an outlaw, it’s referring only to permanents with one or more of the creature types specified above. Notably, it’s not referring to any spell or card not on the battlefield. However, other abilities may refer to an “outlaw spell” or “outlaw card” in a zone other than the battlefield. Those abilities refer to spells and cards with one or more of the specified creature types.

You pay all costs and follow all normal timing rules for cards played from exile with Laughing Jasper Flint’s last ability. For example, if you exile a creature card this way, you must wait until your main phase to cast it.
