How can we change the mana crystal into health? Can we do this?
I dont think so, but if you select "More..." option, you can add Health cost under the Mana cost. You will need to generate your cards regularly first and then enter the HC link in there, just follow the instructions ;-)
On Hearthcards, is there a way to un-bold a keyword? I think it's not on the OP, unless I missed it.
For instance, if you want to write "Summon a Silver Hand Recruit", it will detect "Recruit" is a keyword and the result will be "Summon a Silver Hand Recruit".
Has this been happening to you? It hasn't been happening to me. I'm pretty sure "Silver Hand Recruit" is specifically coded to not bold the Recruit part.
Some time ago, but yeah.
Anyway, even if Silver Hand Recruit is coded that way, that doesn't exclude other scenarios where un-bolding would be useful. Imagine that instead of summoning a Silver Hand Recruit I want to summon a custom, I don't know, Golden Hand Recruit, Inspired Champion or whatever; or I want to add the spell Silence to my hand.
I think this has also been addressed a while ago, most keywords will not get bolded, unless you put colon behind the text. So "Battlecry: ABC" will be bold, but "Battlecry ABC" will not be.
