The Prerelease for the set will be held the week prior, meaning they could take place any time from June 6-12, 2025
While in theory it can be good against control decks, in most matchups it is too slow (although it can be sweet with Engulf the Shore if the game goes super long, since we can bounce it back to our hand without actually getting in combat damage)
Lands (20) Spells (42) 3 Armageddon 3 Wrath of God 3 Swords to Plowshares 3 Icy Manipulator 4 Howling Mine 3 Winter Orb 2 Land Tax 1 Ivory Tower 1 Balance 2 Earthquake 2 Circle of Protection: Red 2 Island Sanctuary 3 Fellwar Stone 3 Disenchant 4 Black Vise 3 Zuran Orb Sideboard While the first World Championship had been Type 1 (Vintage), the second years were the newly created Type 2 (Standard) format
And since in most sets you only get a tapped creature by having it survive combat as an attacker, these rewards can actually be quite substantial
Some of my top picks include the Latias ex SIR, Latios SIR, Skarmory SIR, and Mesprit SIR
