Do you still get Fire Formation Tensu's effect if it was chained by Mystical Space Typhoon in Yu-Gi-Oh?

Answer 1

Continuous Spell Cards must remain face-up on the field for any of their effects to apply, be they something that applies when the Spell Card initially resolves to the field, or reusable activated effects.

However. Fire Formation Tensu only has continuous effects. If you chain Mystical Space Typhoon to Tensu's initial activation, there's no 'effect' to stop, as such. You can't claim the extra summon until it resolves to the field. Then after it resolves to the field, it has no effect that Mystical Space Typhoon can chain to. When you normal summon, you just say Tensu's doing it, the opponent has no chance to stop this. He has to get rid of it before you get chance to claim the extra summon.
