Rule 359.3.e.14.a

In order for a later linked instruction to execute, its earlier linked instruction must have executed. If the earlier linked instruction is ignored for any reason, the later linked instruction will also be ignored. Example: Hidden Blade reads “Kill a unit at a battlefield. Its controller draws 2.” If the chosen unit changes zones or moves to base in reaction to Hidden Blade, the spell will mistarget and the first instruction will be ignored. If the first instruction is ignored, the second instruction will not execute and the unit’s controller will not draw 2.
