it's "master of the past" in uncommon for holy or alliance decks...I think that the cost should be bigger

Nope. This cards requires to be played after another one. It means you must forsee enemy movement and he can wait for you to play non-specified card to make uncounterable step. Very nice concept.

If you have an alliance/holy deck that could mean almost anytime (like if you had master of past).
I really think that the concept is good but
1) the cost should be bigger or have a if not new condition
2) why alliance/holy? Will there be other flavours?

I think that more uncommom cards could be created based on rare with a similar conditions

the "if not new" suggestion is a good idea. I don't know if this card is too good, It should be tested first.
about keywords: it is alliance becouse I wanted to create a defensive card for alliance deck. it's holy becouse of the name and the imagine I found (sometimes I first find good pics and then I think the effects of the card).
I think that master of the past is the only rare that can be uncommon adding a condition like this, all other rares will be too powerful.

That makes me ask:
Why did you want to make a Def card for Alliance? It's not like they son't have enough of them already.

good question. I don't use mountain sentry becouse I feel it overpowered (I use it only if I get it by ranger). and darwen fortification is good but too expansive (there are lot of brigand decks and fast attack decks lately).
well, maybe alliance doesn't need another defensive card but more is better then less.
The original idea was named "elven ritual" but I didn't find a nice pic for this name.

I agree with Xpoh, I don't think this card is imbalanced. Definitely an interesting idea.

It still feels the conditions are easily met. Especially if you are playing in Hidden mode. I think giving it a higher cost would be good.
