Right, for some reason I thought Quicksilver Dagger dealt the damage, not the creature.
Surely you could use the combo anyway, as (effectively) milling 20 to win sounds fine to me?
Overload is an alternative cost, not an additional cost, so 117.9
["If you cast a card "without paying its mana cost," you can't pay any alternative costs. On the other hand, if the card has additional costs (such as kicker or multikicker), you may pay those."]
does not apply here.
Sorry to be a party pooper, but doesn't Unburial Rites not work on Worldspine Wurm even with Hypersonic Dragon? Here's how I see it:
1. Worldspine Wurm enters the graveyard
2. The shuffle effect is put on the stack
3. Unburial Rites is cast and put on the stack
4. Unburial Rites resolves, putting Worldspine Wurm on the battlefield
5. The shuffle effect resolves, and Worldspine Wurm is shuffled back into your library.
