The problem boils down to that most-fascinating of subjects: MTG card templating
This card is the reason why the format is balanced: as I said before, combo decks like Creativity and Belcher play various disruption spells (for one mana Veil of Summer, for zero mana Pact of Negation and Teferi, Time Raveler) so Force of Negation is the best answer to back up another counter, due to its unfair cost
Tierlist No Rank Grade it yourself About The Wind Crystal The Wind Crystal, Legendary artifact, designed by Minoru first released in May, 2025 in the set Final Fantasy and was printed exactly in 3 different ways
Theros Beyond Death introduces a new way for UR to play, one which Vexing Gull enables and does so without being a noncreature spell
Theres also a class of 0-mana suspend spells like Crashing Footfalls and Ancestral Vision that technically fit the definition of a cheap instant/sorcery, but fall outside the scope of this list since you cant fire off the spells at will
