Partner ideasfor snowy Castform

Ice

Pairing ideas, not prescriptions — ideas to test, with every reason traceable. Each card sums up what the partner does for Castform: completing its plan, patching weaknesses, breaking walls — and how often the two already team up in ranked play. Downsides sit under the card, never hidden. Open a card’s Partnership Report for every reason.

What holds up

Every reason is derived from the pinned dataset, never written by hand
Coverage, resistances, and role gaps are calculated per pair
“On X% of teams” is counted from ranked play, not estimated

Still growing

Not exhaustive — partners that work exist beyond what these rules reach
Some pairings are theory or niche rather than something you meet on ladder
The order is a ranking heuristic; the reasons are the evidence, not the rank
