Let's say you could only have one card, AND ONLY ONE, you have 1000 health, and a bit of resist, what spell would it be. Also, you have a dragon blade. Every card could fizzle, except those that don't attack. ANY CARD, BUT YOU ONLY HAVE ONE IN YOUR DECK. Well, which card?
Triton
Storm Lord
Wild bolt
Fire Dragon
Wraith
I'd choose RESHUFFLE. Because it doesn't fizzle, and if you are close to dying, you just reshuffle and you still have a card.
