Interesting Dispel Magic Questions

[Witty Username]

while ignoring that Summons and Conjures allow continued control (sometimes even via a BA) over the creatures summoned/conjured. Is the control over the creatures not a magical effect of the spell cast?

There is an argument to be had whether the contol aspect of summons is part of the creature summoned. Especially with the Tasha's spells as they are more spell effect than creature.

A better example would be animate dead, which both creates an undead creature permanently asserts control over it for a period of time.

I would say any spell that allows telepathic command to be dispelled by targeting the caster definitely.
