Same story with my Scrap-"Metal" dragon a.k.a apple wester.
Not a single win against a Champ. Yesterday I fed it up to LV.15 was LV.12. I put so much faith in him but all for nothing. Corrupt Stalwart Dragon is furious opponent and I think hi is the end of the road for me...again.
Now I'm with 200k apples less and a piece of fat S'crappy loser on the bench.
I'll keep trying, still in need for 7 more dark crystals. My Amazon 15, Sphinx, Apprentice, Ice G failed against Corrupt St.
