Format definer? Starlight Road

For those of you who don't know what Starlight Road does, this is the translation : Activate only when an effect was activated that destroys 2 or more cards you control. Negate that effect and destroy that card. Then, you can Special Summon 1 "Stardust Dragon" from your Extra Deck.

Many think this card will be a format definer and for good reason. Turning an opponents Heavy Storm, Judgment Dragon, or Gladiator Beast Gyzarus into a Stardust for you and a card lost by the opponent is game breaking. Look for more people to be playing Giant Trunade, Cold Wave, Dust Tornado, Phoenix Wing Wind Blast, and other cards that will neutralize the impact of this card. Remember this card is a horrid topdeck, and is useless if an opponent plays around it. The risk reward is high though so look for this to be a staple at one in every deck, just to scare opponents if nothing else. Just seeing this game one in the mainboard will make an opponent think you might have it game two, even if you have sided it out in favor of a more useful card.

It might also reduce the playability of Mirror Force and Torrential Tribute. Many may play 3 maindecked Dimensional Prisons instead, and maindecked Trap Holes on top of Bottomless Trap Hole. In other words one for one card trade cards like Fissure and Smashing Ground.
