If I activate Temporal Portal's ability and play Hidden Blade with Repeat, targeting the same unit (Stalwart Poro) twice, and it dies, do I draw 2 or 4 cards?

Ruling: This interaction lacks clear resolution in the current rules. The community is divided between two interpretations with no official answer yet.

Two Main Interpretations:

Draw 4 Position:

• The spell moved the unit to a different zone, so rule 356.3.e.13 allows the spell to "look back" at the unit's characteristics (including its controller) for all instructions within that spell
• Since Repeat creates one spell that executes instructions twice, both "its controller draws 2" instructions can reference the same target's information
• The spell as a whole caused the zone change, so all instructions can access that information

Draw 2 Position:

• Target legality should be checked as each instruction executes, not just at the start of resolution
• The second "Kill a unit at a battlefield" instruction has an illegal target (unit is already dead/in trash)
• When the target becomes illegal, "its controller" returns null per 356.3.e.12
• Each targeting choice creates a discrete block of instructions that must independently verify target legality

Nuances:

• This same ambiguity affects Hidden Blade + Zhonya's Hourglass with Repeat (does the unit die through Zhonya's on the second kill?)
• The core issue is whether 356.3.e rules check target legality once at resolution start or continuously during resolution
• Rule 356.3.e.13 may be overly broad in allowing spells to reference units they moved
• The phrase "by the time the spell is finished being played" in 356.3.e is ambiguous
• Riot has acknowledged the thread but provided no official ruling yet
• This will likely be addressed in a future Comprehensive Rules Document update or FAQ
