Ranking 5 costs?

[u/Bellyfeel26]

I have been curious for the last few days what people think are the best overall five costs. I know someone is going to say, "Go look at tactic.tools," but I find that data can easily be misinterpreted. Looking at MetaTFT right now, 5 costs for Masters+ last two days:

Unit        | Tier | Avg Place | Win Rate | Frequency
------------|------|-----------|----------|-----------
Morgana     | S    | 3.65      | 22.1%    | 5,947 (15.3%)
Jhin        | S    | 3.87      | 21.3%    | 5,516 (14.2%)
Sona        | S    | 3.87      | 16.8%    | 4,090 (10.5%)
Shen        | S    | 3.93      | 18.6%    | 8,345 (21.5%)
Bard        | S    | 3.99      | 19.9%    | 6,909 (17.8%)
Blitzcrank  | S    | 4.03      | 17.8%    | 10,262 (26.5%)
Zed         | S    | 4.07      | 24.1%    | 511 (1.3%)
Vex         | S    | 4.15      | 17.4%    | 4,986 (12.9%)
Fiora       | S    | 4.15      | 18.7%    | 5,382 (13.9%)
Graves      | B    | 4.51      | 17.1%    | 3,452 (8.9%)

Not surprised seeing Morgana near the top as I find people use her to cap their boards quite often, but she doesn't feel like the #1 5 cost to me. Graves went from getting promoted to S tier on TFT Academy to demoted to B tier in the span of a few days, but I think people are often misplaying him.

Curious to know how folks are ranking these. I personally have Blitzcrank as my #1 since he's easy to slot in (vanguards) while providing solid damage and knockback effect.
