Since Corrupt Stalwart is a Champion/Dark type, and the Dark Type has no weakness or strength, meaning it contributes nothing (which is why higher levels and rarity tiers work best), he should be treated as a Champion, as that's the only type that makes a difference for him. Similarly, as Corrupt Artifact is a Dark/Green/Black hybrid, fighting then is the exact same thing as fighting a regular Artifact Dragon, therefore they should be treated as such.

Since Corrupt Stalwart is a level 20 Champion, you should stop levelling up your Glasswing for now and level up your Diamond (they're actually among the cheapest dragons to feed anyway). That's the only way you'll stand more than a 10% chance against him. And anyway, Glasswing already falls under the Ultra Rare tier instead of Unbreedable, so even at level 11, she'll still be very strong (mine is, and she's also level 11).

Best of luck!
