So I'm thinking of tweaking my Merfolk modern deck. Aside from {Mana Leak}, what are some good counters/instants/whatever I should keep an eye out for?
{Remand}
{Spell Snare}
{Spell Pierce}
{Cryptic Command}
{Cursecatcher}
You could {Muddle the Mixture} or tutor one of your Merfolk. Unfortunately it does not hit creatures.
Don't forget {Dispel}! Also {Echoing Truth} is so boss against token decks, especially infinite token combos. "Oh no! You just made 1,000,000,000 tokens!? Its too bad it was all for nothing..."
{Cyclonic Rift} is actually quite good.
{Vapor Snag}
