The counterspell suite should look at Arcane Denial, Counterspell, Fierce Guardianship, and the modal card Sink into Stupor (another bonus land option), though you can modify this for your preferred counterspells, with the focus being stopping spells that can remove Captain America or key equipment

You might even think about building out from this deck using Clarabelle Light on Her Hooves
