Since both cards share similar value and were distributed for the same event, this one was chosen as the less visually vibrant option, making it more average-looking
This opens the way for Instant/Sorcery synergies like Primal Amulet, Increasing Vengeance, Pyromancer's Goggles, and Howl of the Horde to copy our sources of burn
The deck has no shortage of other burn cards on top of The Lord of Pain to make sure you can close out games
With this system, theres quite the discrepancy between the options here value-wise
Not quite the traditional Fling effect (here your opponent can remove the sacrificed creature in response to casting the spell), but it has upsides in that the creature itself deals damage to the target, so deathtouch or lifelink will work (as will abilities that trigger when the creature deals the damage)
Using Energy Removal to reduce Chansey's Energy from three to two can prevent this, giving players a brief chance to recover
