Of all the Summoners, I like the Dragon Splinter Daria Dragonscale!
Yes, she has a flaw: it is 4 Mana points (compared to Starter Paсk Summoners with their 3 Mana).
But she can call for different Splinters + she can summon more Leveled Monsters cards!
So, while the Starter Pack Summoners is enough expensive to buy for the upgrade - the Daria's upgrades are may be used for all Splinters.
It is a pity that there are no daily quests to pass by Dragon Splinter.
I also did some polls about Dragon Splinter cards:
How often do you meet rivals playing Dragon summoner?
How often do you meet rivals playing Dragon Monsters cards?
Join the Steem Monsters if you still have not!
