I'll analyze the winrate performance of Ruby Storm and Eldrazi Ramp, then identify common weaknesses for both archetypes.
Now let me check specific matchup data for both archetypes against the top meta decks:
Overall Performance (Last 60 Days):
Ruby Storm has a +3.7% winrate advantage overall, performing above the 50% mark while Eldrazi Ramp is slightly below even.
Both decks struggle significantly against these archetypes:
1. Neobrand (All-in combo)
2. Azorius Control
3. Grixis Reanimator
Ruby Storm's Achilles' Heel: Control strategies (particularly Azorius) shut down the combo with permission and sweepers. Domain Zoo (34.15%) and Blue Belcher (40.0%) are also problematic.
Eldrazi Ramp's Struggles: Fast combo decks like Neobrand are devastating, and graveyard strategies (Grixis Reanimator) exploit Eldrazi's inability to interact on the stack pre-board.
Shared Weakness: While they both struggle with different aspects, Neobrand punishes both - it's too fast for Ruby Storm to race consistently and completely bypasses Eldrazi's gameplan.
