No matchup data available for Simic Omniscience vs UW Control or 4c Control in the past 30 days. This likely indicates these specific control variants haven't faced Simic Omniscience in recorded tournament matches, possibly due to the archetype's low 1.0% meta presence.
The data shows Simic Omniscience performs well against slower midrange strategies but struggles with aggressive decks, suggesting control matchups would likely favor the combo deck's ability to assemble its win condition.
