EVO= playing in evo style - mostly in Lost Warehouse. Meaning the player that plays the card first play 6 pillz with it... same in all following rounds. Exception is generally made if one would KO the other one this way - in which case the other player plays 6 pillz. This is a method to gain XP for cards mainly (not exclusively. My personal opinion is that this playstyle outside the warehouse is ridiculous and I ignore it in torunaments if I get challenged by them). Nice playing in the warehouse consists of pairing low level (star-count!) cards with high-level cards - regardless of who will win, this gives the most xp to BOTH cards. Inherent in Lost Warehouse EVO is also not trying to win. If one boasts about winning in the Warehouse he just proves himself to have not understood a thing. It is easy winning against people who do not try to win ,)
That was extensive as it carries certain connotations in the Warehouse. There is another thread (pinned?) more extensively about this. In short: EVO means playing 6 pillz when you play the card first and your opponent waits, 0 in the other case. [most people consider other numbers ok as long as you do not play any pills when your opponent plays first]
OLD: no pillz used at all
CR: um, I have to pass. Usually it stands for "CollectoR" in cards.
Quite some suffixes also refer to being member in a clan.
