wraith+ deer knight= diseased executioner baby curse, ancient sharpen blade, ultra death trap
spiny fish+ siren= zapped siren adult storm beetle, mega stormblade, ultra spark of life (5 pips) (940 health)
Let me know what you thing and if you like the idea do me a favour and charm it. If you're angry about the ultra skills it is just to get people to actually train pets to ultra.
