Does Blitzcrank remember his location when his effect activates, or is 'here' re-evaluated at resolution?

Ruling: 'Here' is always evaluated at resolution, not when the effect is created or put on the chain.

Sequence:

• Blitzcrank's ability triggers and goes on the chain
• When the ability resolves, 'here' refers to Blitzcrank's current location at that moment
• If Blitzcrank has been moved or killed, the location reference changes accordingly

Nuances:

• If Blitzcrank is killed before resolution, there is no 'here' and the ability resolves without effect (the unit doesn't move)
• If Blitzcrank is moved to a different battlefield, the pulled unit moves to that new battlefield
• If Blitzcrank is moved to base, the pulled unit would recall (since units can't be moved to an opponent's base)
• Blitzcrank cannot target a unit already at the same battlefield, but if moved to the target's battlefield during resolution, nothing happens (the unit doesn't move because it can't move to where it already is)
• Rule 436.2.b only applies to the specific case where a unit tries to enter a battlefield with combat between two other players, causing it to go to base instead
