Judith, the Scourge Diva
If the idea of burning your opponents down with the help of spells doesn't sound too exciting, then you could focus on an alternatively aggressive approach, except with the help of creatures.
Rakdos and Mardu Aggro lists that run a lot of cheap creatures, such as Fanatical Firebrand and Legion Warboss, will have a blast playing Judith. She can buff all those tokens with haste and win through sheer pressure. And if one of the non-token creatures dies, then you can use her second ability to ping your opponents for even more damage.
This type of gameplay requires a bit more strategic thinking than your typical Burn deck, but that's what makes it so much more fun.
