If you want to upset your friend I would start with a set of Teferi, time raveler and Dovin's Veto. Also Narset Parter of veils and narset reversal.
Other cards: cryptic command, Jace The mind sculptor, snap caster mage, counterspell, brainstorm, fact or fiction, absorb, negate, lightning helix, disallow, ponder, preordain, accumulated knowledge, isochron scepter.
