@St_Shiro if by your question you mean can you play a card with the phyrexian symbol in any deck, no, the color of the symbol reflects its color identity.

Solid card... Shuts down aggro.. Helps win games and save you. 2 Mana. What more do you want?

Extort is great in 2HG. 
for a four point swing? Yes, please.
This sitting on the board doing work for several turns also exposes how many decks are built to go for it without considering removal. Four please... and an Argivian Find to help keep this in play.

Ben Franklin once said "haste makes waste." That's what this card does.

Can steal life, screw up most combo decks (if you get a T2) due to messing with artifact mana or screwing up Sneak Attack, and helps get your creatures through as you control the board. Also helps with Bloodbraid Elf and other fast cards.

Great sideboard cards in aggro matchups, also counters Splinter Twin / Kiki-Jiki combo decks. 4/5.

@RAV0004
Extort is legal in a mono white or black deck because the hybrid colors are in the "reminder text". The ability is reminding the player you can either pay white or black mana for it. Im very confused though, how you said first strike is a white and red ability? There are first strikers from every color, and the ability doesnt have a cost anyway?
So, Extort is LEGAL in mono white or black decks
