Modern Horizons has a couple of really exciting counterspells, such as Force of Negation and Archmage's Charm. The latter one is a bit more flexible and guarantees a card draw in case there is an extra copy of it in your hand already.
It has a slightly off mana base that requires you to have three islands, but if Modern players managed to successfully cast Cryptic Commands for so many years, then they will surely find a way to cast Archmage's Charm.
The third ability is also quite good and allows you to steal Aether Vial artifacts from opponents or their tokens. So there are a lot of cool things happening here for sure.
