Are Playstyle cards relevant?

[Field Emperor]

I mean, they affect your player if he is used by CPU, but if you use it, obviously, what effect does it provoke on the gameplay?

The reason for this, is that I made a player very recently without a playstyle card and I came to realize this, and because the rolling system often gives you more Special cards if playstyle ones aren't avaiable for your position + mould...

For example, AMF with "All around" never gives you a playstyle card.

The only ones I can think off have description and are bold.

P01 - Classic No.10 (AM) (Offensive)
An old-style static playmaker who makes use of deft touches and passes rather than pace or movement.
(better passing skills?)
P02 – Anchor Man (DM, CM) (Defensive)
P03 – Trickster (RB, LB, RMF, LMF, AM, RWF, LWF, SS) (Offensive)
A skilled dribbler who uses the step-over to great effect in wizarding past the opposition.
(doenst need explanation, better dribbling skills?)
P04 – Darting Run (RB, LB, RMF, LMF, AM, RWF, LWF, SS) (Offensive)
P05 – Mazing Run (RB, LB, RMF, LMF, AM, RWF, LWF, SS) (Offensive)
A great dribbler whose quick turns and dummies are a handful for any defence.
(more dribble skills?)
P06 – Pinpoint Pass (SW, CB, RB, LB, DM, CM) (Offensive)
A long ball expert who can play quality passes from deep.
(more passing quality?)

P08 – Box to Box (DM, CM, RMF, LMF, AM) (Offensive)

P12 – Goal Poacher (SS, CF) (Offensive)
P13 – Dummy Runner (SS, CF) (Offensive)
A player who attracts the defence to create space for other players to exploit. (maybe the defence follows you more?)
P14 – Free Roaming (CM, RMF, LMF, AM, SS) (Offensive)
P15 – Talisman (CM, RMF, LMF, AM) (Offensive)
The talisman who can drive the entire team forward.
