Quick question. This caused an argument at the hangout, and tempers were flared. Here we go.

Player A has a set Bottomless Trap Hole and Starlight Road. Player B has a set Dust Tornado.

Player A activates Heavy Storm from his hand.

Player B doesn't chain.

Player A chains Starlight Road.

Player B chains Dust Tornado, targeting A's set BTH.

If this chain is legal, does Starlight Road resolve properly? Correct or not, what happens?

Starlight Road should be able to resolve as normal because its activation requirements have already been met (a card effect that would "definitely" destroy 2 or more cards Player A controls). Nothing in rulings that I can find saying that the effect in question must destroy 2+ cards of Player A's when it resolves as well.

Yeah, same here, Half. Can't find anything about Starlight Road requiring its conditions to be met at activation and resolution. Thankfully, no blood was shed that night. Whew. It sure was one heck of an argument.

While I'm still here, I have another question, and I'll ask it here instead of starting another topic. Player A's Machina Fortress and Player B's Lightpulsar Dragon destroy each other in battle. Player A uses Fortress's destruction effect on Player B's set S/T. Can Player B use Lightpulsar's effect to special summon a level 5 or higher Dark attribute Dragon?

It would go into a Chain with Chain Link 1 being Machiner's Fortress (as it's a mandatory effect) followed by Light Pulsar Dragon as Chain Link 2 (optional) and resolve accordingly, assuming Player B chooses to use Dragon's effect.

Thanks for the clarification, Half.

i heard about this a while ago and wanted to know if it's a true ruling but it's like this
player A: set starlight road and a second card in back row
player B: activates heavy storm
player A: chains starlight road
player B: chains mystical space typhoon targeting starlight road
resolution goes as it should, but the point was that because starlight road was destroyed before resolution player A doesn't get a stardust dragon. T/ F?

The only way to stop Starlight Road would be to negate the activation and/or effect (Dark Bribe, Seven Tools of the Bandit, Royal Decree, Special Summoning Jinzo later in the Chain, etc). Otherwise, you can at least prevent the Special Summon of Stardust Dragon by making Starlight road unable to destroy whatever it is being chained to in the first place (since if you are unable to destroy the card, you are unable to Special Summon Stardust Dragon as the negation/destruction and Special Summon occur at different times).

Otherwise, in this case, it will still resolve normally because its activation nor effect have been negated and there is nothing that states it must remain on the field to resolve successfully (that only applies to Continuous Traps, Traps that equip to monsters after activation).

It's just like how if one activates Monster Reborn and the opponent chains with Mystical Space Typhoon/Dust Tornado/etc and targets that Monster Reborn and destroys it, that doesn't prevent that Monster Reborn from resolving because it was still activated successfully.
