For a new ability, I wouldn't mind seeing Switch. Example: Switch: Opp. power and damage. For example, Ielena would be at 3 power and 8 damage. This could be an advantage since Ielena would be easier to beat, but it can be a double-edged sword if she were to somehow win and get all that extra health. Or if someone is using Caelus Cr and you don't want to take a lot of damage, just use switch, his damage will be 4 and let him win.
This would work better with the Piranas or Nightmare, but Switch opp ability and bonus can take away a character's ability since with the clan's bonus. Or if a GHEIST/Roots member wants to overcome a Montana's pesky bonus, using this ability would take that way since it's now an ability they can cancel.
Of course Protection would negate it. It would also be useless against cards with matching power and damage scores like Cortez. Imagine how evil a Pirana/Nightmare with Switch: ability and power against Skeelz. With the Skeelz member's ability now becoming their bonus, Protect: Ability can't save them.
I think we have the right amount of ability types in this game. Any more and it could start getting really convoluted, which isn't good- compared to other card games I've played, UR is relatively easy to pick up and understand whilst being interesting and entertaining. Let's keep it that way
I was thinking more along the lines of swapping values.
Say a card with 3 damage had Switch: Damage. The opp base damage becomes 3 and the card's base damage becomes that of the opp.
Protection would negate the effect, value=opp value would neutralize it.
Also manipulation comes into play.
Let's say a 5 power card swaps power with a courageous Quinn. The card would get 6 base power reduced by 2 and Quinn's power would become 5+2.
Let's then say a 3 damage card swaps damage with Jane Ramba Cr. Jane's damage becomes 3+2 and the card's damage becomes 4-2.
What I'd like to see...
Guild map and fighting over turfs over global map. You'd try to capture areas and keep them. You could commit "decks" to map grid and those decks would be used in defensive/offensive purposes. Farther away you are from your base the more penalties you get when fighting so conquering whole map would be quite impossible. Each week guilds/members would get rewards depending how large area they control / how active they have been on "global map" game.
For added twist you could try to snatch cards from opponent decks in global map by accepting additional penalties to your game. So if enemy puts up high profile deck defending some remote location, you could try to capture one of the card by beating that deck. This would limit how strong(expensive) cards would be used in global map because it would pose a risk to lose those cards. Snatching cards would not be easy feat, but it would put pressure into making efficient decks.
This kind of high-level-meta game with decent risk-reward system would blow totally new steam to this game.
The only real flaw in that plan (of doing a player/guild-driven ongoing territory control ala Eve Online) is that there aren't any good long-term time and money sinks worth the effort for all but the most neurotic, bleeding-edge players.
Having map control where different parts of the map used different formats and pill/life counts would be cool, but there's no incentive for players to play it, except maybe if there was an overhaul of the Collector system.
