next: bonus if you can make it a hero card but not necessary

I like the first one better but I would change the coma to an and, also the number 3 is good.

So far people are suggesting that the Malchezaar, the Terror card cost 5, 8, 9, and 10. This …

Should this cost 8 or 9, and is it better in Saviors of Uldum or Mean Streets of Gadgetzan? It might be better to give your opponent random legendaries to dilute their deck but on the other hand against aggro …

Replying to above I think Millhouse is too strong, Hogger is great, and Hakkar is probably too weak especially against control decks where you can never play it but may be good against aggro with a plague of flames combo.

You can use it on your own minions for extra damage or for some combo, or on your enemy minions if necessary as removal.

Next: a legendary dragon with a powerful effect

That’s true, [card]Twin Emperor Vek’lor[/card] is a C’thun card but it’s weak in wild, and you can replace [card]Bandersmosh[/card] for removal or card draw. It’s mostly there for fun and to have the ability to highroll tempo against unfavored matchups. 

next: a demon hunter card

My main question is how to balance this properly.

Thanks for all the comments! I changed it to a warlock card with a new image

This is the first time I am trying to make a custom card. Is it balanced/makes sense?
