My thoughts on changed skills:
Evasion: Make it 'turn off' when you fortify, like was suggested and I think we are at a good spot. Question: If I aggressive charge a person with evasion, do I move and not attack, or does my movement AND attack fail?
Energy Barrier: Consuming a relic seems a bit high for what it does. You have to preemptively use it, assuming your town will be seiged... and if it is not, you are out a relic and 2 AP. I think this all depends on my understanding of relics. aside!
Relics!! Here is my understanding of these little guys. They cost about 1/4 of a card and can buy them in any (?) city. You can carry 5 items total, these count within that # and do not stack. They are used for abilities and nothing else. Is that about right?
So.... if you are in a city defending it, I guess it is not that bad to use a relic... and after 4 days of defending, buy a whole bunch more. If these assumptions are correct, then... yea, it's good now. One person blocks two people's siege.
Random suggestion as I write this! We should have an ability or town improvement, etc, that allows when seiging a town to cut off their source of cards or relics. A blockade ability. This way the town you are hitting can't use the above ability to, you know, stay behind a forever powerful wall.
Debilitating Beam: Much better. I like YoungSot's suggestion to also targeting a T3 ability. Or, it could also disable all T1, T2, including passives. That could be fun, would lead to some good counter play against strong passives, and allow you to attack while they are 'disabled' and gain an advantage from people who gain upped cards with skills! I find the 1 day too short as is, but that leads to another Question: Skills like this one and caltrops, does the de-buff happen to the opponent's next turn or current turn? Example: I use DB on YoungSot on day 15. Does that cancel any of his Day 15 T1 and T2 planned actions or does it disallow him from using them on Day 16?
Champion of Aether: Very smooth. Super fun. I'm assuming you can re-summon until you get the Horror you want? (some fun RNG here in play.) Do you duel with your guy's deck or do the NPC guys? Is it randomized each duel or when the lil' guy spawns? What if players use discarding abilities on the lil' guy? is he immune or does he die when he hits <30 cards?
