Please stop breeding and feeding airs. It's a waste to work on a single element dragon.
So, I assume you want a plan for Gold Shrines, as Silvers are nearly done? You need:
43 Plant
44 Water
41 Earth
35 Fire
46 Metal
44 Cold
44 Lightning
44 Air
341 Elements.
So 41 Panlongs to start. This will get your Airs to silver and quite a ways to Gold.
43 Plant
3 Water
46 Metal
44 Cold
44 Lightning
3 Air
Tidy up the Air and Water with 3 Rust, 2 Snow and 1 Sonic. Leaving
43 Plant
43 Metal
42 Cold
43 Lightning
43 Magnetic and 43 Lichen/Reindeer will finish it up (or a Plant instead of that last Lichen if you prefer). So
41 Panlong
43 Magnetic
43 Lichen/Reindeer
3 Rust
2 Snow
1 Sonic
133 dragons to knock off 341 elements in the most efficient manner.
