Does Karthus see itself when equipped with Sacred Shear, causing it to draw 2 cards instead of 1 when it dies?

Ruling: Yes, Karthus sees itself when it dies with Sacred Shear equipped, so it draws 2 cards total (the Sacred Shear deathknell triggers twice due to Karthus's passive).

Sequence:

• Karthus dies while equipped with Sacred Shear
• Karthus's deathknell goes on the chain while Karthus is still on the board
• Karthus's passive is in effect at this time, so it triggers twice
• You draw 2 cards total

Nuances:

• This is similar to how Karthus doubles deathknell effects of units that died together with him
• This ruling differs from blue Viktor's interaction, which works differently despite seeming similar
• Karthus is considered a "weird niche card" that doesn't work like the game engine would suggest
