Forum:Smashing ground vs stardust dragon

Alright as far as i understand, It dosen't matter what way stardust is summoned as long as he's on the field you can use his effect, Someone tells me "if you brought out stardust with starlight road and i use smashing ground its it stays in the graveyard either way"

Am i missing something here? why would stardust not come back if i activated the effect? Or am i right and he's just delusional? lol.
