Do I get my Legion effect when I play a token or use an ability?
No, Legion will only be active if you've played a card this turn. Tokens are not cards, and abilities aren't either.
When I hide a card, does that count for Legion?
Hiding isn't playing, and doesn't count as playing a card for abilities like Legion.
Can I use Sun Disc's ability the turn I play it, counting itself for its Legion ability?
Yes. Although Legion normally requires “another" card for spells and play effects, Sun Disc's activated ability is not Sun Disc. On subsequent turns, you'll need to play another card to turn on Legion.
If I gain control of my opponent's Stupefy with Rebuttal, does Ravenbloom Student trigger? What do Battering Ram and Legion see?
Ravenbloom Student triggers (twice, counting your Rebuttal) because it checks whether a spell you control resolves — and the stolen Stupefy resolved under your control. Battering Ram and Legion instead check who finalized cards: you never finalized Stupefy, so your Battering Ram only gets a discount for the cards you finalized yourself, and your opponent's Legion abilities remain active.
