Yet another question:
When I reveal a Spell or an Epic Spell with Xirat'p's ability, do I need to obey other restrictions (e.g. Cacophonic Scream's "Play at the beginning of your turn.") or do they only apply when playing them normally?

Ok, two more questions:
1. How persistent are granted properties? Does they last when an unit granted an ability goes to the graveyard/hand and then reappears in the play? E.g. Does Countess Iseara turn Crypt Ghouls/any 0-cost unit into infinite sacrifice fodder?
2. What happens to trigger conditions generated in single action chain? Are they grouped in the newly created action window or can I respond to all of them even if they're similar? E.g. How many resource counters can I put on my Heroic Task staffed with Thief of Essence when I play Whip the Slaves on my Walking Sacrifice?

1. Does abilities on units trigger when they leave play as development? e.g. Crypt Ghouls, Zhufbar Engineers
2. Does Forgotten Cairn trigger when an unit leaves play as development?
2. Can i use Kindred of Laith-Kourn's ability when there is no damage on him?

It doesn't come often, but it comes in handy when you create mixed factions decks.
Also having cost as integer instead of string would stop putting 10 cost cards between 1 and 2 wink

As in topic - WHI lacks the functionality to order cards by loyalty.

Could you please add city 'Ostroleka' in vovoideship 'mazowieckie' in country 'Poland'?
