Maarika forces your opponent, and no one likes being forced
Ive often talked about redundancy being one of the key measures of a decks success
While Aurelia is a legendary creature and can be used as a commander, she only has 313 decks to her name, which isnt a substantial enough number to demand such a premium based on it being a popular commander someone would want to bling out
This also counters most red instants and sorceries, the odd one from other colours too
Furthermore, due to this sets scarcity, many of these cards have not reached the publics consciousness fully though notable cards like Fellwar Stone, Ball Lightning and Tormods Crypt all debuted in The Dark, alongside Sorrows Path, arguably the worst MTG card of all time
Creatures like Steelburr Champion and Sunscorch Regent gain +1/+1 counters as your opponents play spells , a sneaky way to force them to repay you for all the gifts you've been giving them
