head to head
Teamfight Tactics asks more than Inscryption, and the gap is variance.

Optimization · Pure Optimization
A meta deckbuilder where engine-building beats the scripted opponent.

Optimization · Systems & Chaos
An autobattler decided by economy curves and shop variance management.
Inscryption leans Optimization (Pure Optimization); Teamfight Tactics leans Optimization (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Inscryption
No reflex demands; turn-based card play.
Teamfight Tactics
No mechanical inputs of note
Teamfight Tactics leans a little harder on reads, though the gap is small.
Inscryption
Scripted opponents with light bluff moments, not true adaptation.
Teamfight Tactics
Scout opponents but no live adaptation
Teamfight Tactics leans clearly harder on variance.
Inscryption
Card draws and event choices randomized.
Teamfight Tactics
Shop rolls and augment offerings swing lobbies
Teamfight Tactics leans a little harder on optimization, though the gap is small.
Inscryption
Deck construction and sacrifice math drive victories.
Teamfight Tactics
Econ curves, positioning, and comps are near-solved
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
