Hi SkyPoppy
I clicked through your dragons and you have a lot of cave born (CB) and purebred (PB) dragons which are great for starting lineage projects.
Nothing on your scroll is super rare or anything like that but nice clean dragons for breeding are a good start to a scroll.
Some useful dragons you might want to hunt for are:
Thunder, Magma and
Ice Dragons are rare dragons that make up the "Legendary Trio". Together, they have the BSA of "Summons". You have to own all three to use this BSA. When successful this BSA brings a "Guardian of Nature" egg to the users scroll.
Red, it has the BSA of "Incubate". This action allows youwarm your eggs to help eggs hatch 24 hours faster.
Pink, it has the BSA of "Influence". You use them to help eggs to gender the way you choose.
Purple, it has the BSA of "Fertility" which increases the chance of getting an egg from the dragon of your choice.
Magi, it has the BSA of "Teleport", useful for trading and gifting.
Aeon, it has the Breed Specific Action (BSA) of "Precognition". This action allows you to see the gender of an egg prior to hatching or influencing.
White, it has BSA is "Ward" to protect eggs from egg sickness for up to 6 hours.
There are some Hybrid dragons you can only get through breeding and you already have some of the dragons needed for that.
If you check out
this link on the Dragon Cave Wiki and scroll half way down that page it shows the Rare Dragons and the Dragons you can only get by breeding. Some are Alts and some are Hybrid.
Hope that helpd you!
I have a post on this thread where I give away these kinds of dragons for free and you can always find them in the AP or the Biome Caves.
Good luck!
