Scenario number two, which I call the fallback option, has a chance of 8.51%
We'd have to make the tokens easy to write on, make it clear the tokens didn't "legend rule" each other, and add a lot of legendary-matters effects
Some of the best cards that work with Vial Smasher include those that add extra damage for your spells, like: Angrath's Marauders Guttersnipe Solphim, Mayhem Dominus 5 General Kreat, The Boltbringer A Powerhouse In The Command Zone A lot of Goblin decks revolve around getting out a ton of tokens or by dealing tiny amounts of damage either all at once or over the course of the game
The second most broken thing you can do is cast a turn 1 Hypnotic Specter, which isnt actually a very good play in a lot of situations, as you are setting yourself up for a 2 for 1
You can only play this spell during your end step
I turn around and see nothing, yet I know it is behind me
