Swords and Repeal should be enough to fight early aggression.
FoW + Spell Snare should be enough to fight one or two Oath's being cast too early. Repeal and Azorius Guildmage should fix anything after round 3-> .
Black Lotus Im not really sure of. Its really nice with Jace and for shocking a stax-player round one. But if the meta would/should be low in workshop Id run something else in that slot (cantrips!).
Karakas has taken Librarys slot. Not really sure if both should be included seeing as this version has Standstill. Strip Mine is also a possible sweet answer.
Standstill is great with all the instant cast critters and removals.
Stoneforge into Batterskull decimates Stax. If you can keep you Stoneforge alive they dont stand a chance.
Aven Mindcensor & Vendilion Clique are goodstuff but you only really want them cast once each.
