When playing Teemo Strategist from hidden during an attack on Fortified Positions (with Viktor Innovator in base), what is the correct trigger ordering, specifically when do Viktor's and Teemo's triggers go on the chain?

Ruling: The ordering described is correct. After Teemo resolves as a permanent, both Viktor Innovator's trigger and Teemo Strategist's defend trigger occur simultaneously, so you can choose the order they go on the chain.

Sequence:

• Ahri Inquisitive's attack trigger goes on the chain first (opponent is contesting)
• Fortified Position's defend trigger goes on chain (target must be chosen immediately)
• No reactions can go between attack trigger and defend trigger
• Attacker has priority and passes
• Defender has priority and reacts by flipping Teemo from hidden
• Teemo resolves (nothing can react to a permanent)
• Viktor Innovator's trigger and Teemo's defend trigger both trigger simultaneously and can be ordered by the controller
