So yeah, perfect scenario would be:
draw Halazzi during 3-5 mana period using Master´s Call.
Play Halazzi on 6 Mana
Play Stampede on 7 Mana

I also crafted it yesterday 🙂
I ditched both of the Jeweled Macaw, since stampede is basically what this card does…
Overall I´m not sure yet.. The big unknown is, when do you get this card… at my games it was sometimes late in the deck.. and if it was early it still takes some time to utilize this.. cause I wanted to at least play 3-4 cards with it.. – I lost some games cause I waited too long for the perfect moment..

Sometimes a few more healthpoints would have won me the game, so I did another change and swapped one Macaw and the Panther for two life givers: Lifedrinker

I also changed the Starving Buzzard to Tundra Rhino – I had the feeling that I was drawing too many cards, and Tundra Rhinos charge ability is very nice in certain situations
