If an effect would Summon but your zones fill mid-chain, does the monster stay in the Deck?!
An effect is resolving and zones become full.
Yes. If there is no available zone on resolution, the monster stays in the Deck.
If I activate Smashing Ground and my opponent chains Stardust Dragon, can I chain my own Stardust Dragon to negate theirs?!
Smashing Ground is activated while both players control Stardust Dragon.
Yes. You can chain your Stardust Dragon to negate the opponent's Stardust Dragon, since the effect being negated would destroy a card on the field.
