New keyword: "Defeated" (if opposing minion isn't ready...)

Title^

"Defeated" would mean: "if the opposing minion is not ready / leaves the ready region"

Thinking of the card Rampage, and how I would make it not wallpaper:

Rampage!
Action
Burn a location. This minion gets +1 strength for this action.
As above, and if the blocking minion (if any) is defeated, the action continues.

Shadow Boxing at superior becomes: If the blocking vampire is defeated, the acting vamp burns 1 blood to continue the action.

Matasuntha ( cap) would read: "Whenever Matasuntha defeats a minion, gain 1 pool."

Thoughts?

What problem would this solve?

Less card text in the text box. That's what keywords are for.

Regular reader, infrequent poster. I've been playing VTES for just over a year now, and have been playing regularly, and have introduced a small handful of other players to the game. Let me tell you, text in the text box is a feature, not a flaw of VTES. I've played a lot of other L/CCGs, and the fact that I'm able to understand what almost all of the VTES cards do by reading the text of the card, and I don't have to go hunting through the rulebook, is one of the major reasons why the game is so noob friendly.

I get that if you've been playing the game for 25 years, you don't need reminder text, and can internalize keywords. If you're a new player, it's the opposite. Read the card and you don't have to go flipping through a glossary to remind myself what a keyword does. I don't see having text on cards as a drawback - quite the opposite.

I agree with CrazyCatTim. I'm a newbe and searching for the value of the titles during referendum is the most boring thing about this game. I'm ok to refine card text but not if I have to go through the rulebook to do so.

While i agree that key words are more confusing for beginners, when you will get used to the game you will appreciate that clarity and lack of rules interpretation they bring to the game.
