Sideboard plans with Xantid Swarm
- Enchantress vs. Blue permission (Landstill, Stiflenought).
- Full English Breakfast vs. Stiflenought, Landstill, Psychatog, Tron, The Solution and Dromar Control. Two Xantid Swarm and two Duress protect the combo turn: once Swarm attacks, the opponent can't cast spells that turn.
- Aluren vs. Stiflenought, Landstill, Psychatog, Tron, The Solution, Dromar Control and Stasis. Three or four Xantid Swarm, in nine of ten sideboards: once it attacks, they can't cast spells that turn, so Aluren and the whole loop resolve.
