Hey Mike,
Why do you say Bob Tendrils (GWSx with forces) is one of Fish's worst matchups?
In my testing, I've found noble fish to have an even or favorable matchup vs. GWSx.
Like Egan said, the track record for Fish vs. Bob Tendrils definitly goes in favor of the Strom deck. I was looking back at recent tourneys, all of them with a Top 8 or finals appearence, in the past month and came to the conclusion. Here is how it broke down in order of # of matches:
Noble Fish Mirrors: 4-0
Tezzeret Variants: 4-0
Oath: 2-1
Bob Tendrils: 0-3
MUD: 2-0
Dredge: 2-0
Belcher Combo: 1-0
Green/Red Beats: 1-0
TPS: 1-0
Dark Times: 0-1
Mono Red Stax: 0-1
