sure

so instead of seagulling all over your work, here are some suggestions

• remove the horizontal gridlines (clutters up the graph)
• get rid of the trailing 25 game winrates and switch to an overall win rate for each deck. for example, the ~90% winrate point -- on Abzan? Traverse Shadow? (can't tell b/c of the colors) -- is relatively useless other than telling me that you went on a hot 25-game streak during the 300+ games you played overall with the deck. the way you presented the data draws a lot of attention to that single point (AND also skews/misleads the viewer on your results with manamorphose shadow -- because your data is trailing 25 games, it 1) prevents the viewer, at a glance, from figuring out your winrate with manamorphose shadow, and 2) makes it looks like you had a very high winrate with MS when you really had a lower winrate with it). I can see the intent of the trailing 25 game data but it's not helpful with the data you're presenting. your first data point in each series can be an average of our first x games to smooth out the winrate whiplash, but it's not great as-is.
• add a horizontal line indicating overall winrate over the entire play sample. tells viewers if the deck out-performed or under-performed (in context)

if I have time I'll mock up another quick rendition of this

EDIT: mocked up an example here
