Index Match Ranking top 3

Here is one way to do this.

1.  Add an index and unpivot your data in the query editor.  I mocked up some data to demonstrate.  To see how it works, just create a blank query, go to Advanced Editor, and replace the text there with the M code below.

let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUTICYmMgNlGK1YkGkhAeSNQQLGIIloOJxsYCAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [A = _t, B = _t, C = _t, D = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"A", Int64.Type}, {"B", Int64.Type}, {"C", Int64.Type}, {"D", Int64.Type}}),
#"Added Index" = Table.AddIndexColumn(#"Changed Type", "Row", 1, 1, Int64.Type),
#"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Added Index", {"Row"}, "Attribute", "Value")
in
#"Unpivoted Other Columns"

I called the table "AD"

2.  Make a second DAX table to hold your Rank values with an expression like this

Letter At Rank =
VAR vThisRank =
    SELECTEDVALUE ( RankTable[Value] )
VAR vSummary =
    ADDCOLUMNS (
        VALUES ( AD[Attribute] ),
        "cRank",
            RANKX (
                ALLSELECTED ( AD[Attribute] ),
                CALCULATE (
                    SUM ( AD[Value] )
                )
            )
    )
RETURN
    MINX (
        FILTER (
            vSummary,
            [cRank] = vThisRank
        ),
        AD[Attribute]
    )

4.  Make a matrix visual with the RankValues on columns, the AD[Attribute] column on rows and the measure on values to get this result.
