On the topic of single rolls, I got lucky and pulled a Loch.

Sound like you had a really good luck at new year 
Yeshhh.Rolled the featured egg for 50 gems. I got Vulcaroth, Terrordragon, and phantomainden
(Lol though I wouldāve liked abyssraider)
Got Serapheon from a single, my first legendary ever
Got bane dragon from a single egg roll during the debut egg of vulcaroth.
Nice! I love my Banedragon.
Banedragon is very useful in my pvp setups.
Iāve probably wasted 500+ gems on singles till I realized saving was better (for me Atleast)
I got Shadowyrm, 2x Tiamazus, Doomengine, Sweetfeather and a lot of good SE. I canāt complain for around 35 eggs, even though Sweetfeather is meh.
Update
Azrazel
Rexo
Ā valentine Egg 8 new legs
Incredible luck bro.
Got extremly lucky today (slayer hunters egg event). Always had my eyes on Prismaryx because he provides very good strategical options (in my opinion). Thought, ok, roll those 6 packs, see what happens. I mean Penguinator would have been fine too.
I then just rolled one pack and directly got Prism! 
Aw what, whereās my st. Patrickās festival? Itching to blow some gemsā¦
Easter Egg event perhaps?
