Maybe sounds stupid but i have had amazing results, and its alot of fun.
This would be even better if you own shudderwock, maybe remove Elysiana.
Try to use your invoke cards with quest hero power, otherwise you need to draw them all,
but a late Galakrond is not a problem, use the quest hero power as long as you can.
You want 4x 8-8 when you play Galakrond.
If you get coin, you can try to save it for a hero powered dragonqueen.
