Hello Everyone!
I noticed this week, there was a challenge issued to use the Dragon Splinter. I am very new to this game (4 days in), so I am still learning how the various basic mechanics work, and as such never was recommended to use the Dragon Splinter. This challenge gave a unique opportunity to explore this splinter that varies from all the rest.
What is the Dragon Splinter? At first, I believed this splinter to be a higher mana cost splinter with powerful cards, limiting it to only being useful in high mana challenges or challenges requiring use of only certain splinters (or daily quest of course!). Little did I know that the Dragon splinter allows you to pair with another splinter of your choice, actually expanding your options!
Excited by this concept, I rushed in to take on a few battles. My first battle did not go well, with Drake of Arnak not helping well against an Alric Stormbringer magic based team in a poor matchup. However, my next battle was a well fought affair!
I came across a master of the death arts, 
The matchup was ready to go!
In reviewing the matchup, Drake of Arnak was clearly a great choice for my opponent. Every enemy took at least 1 extra hit due to the extra armor, and this extending every summons life and kept his team going much longer. However, Unicorn Mustang and Wood Nymph put in a ton of work, and this simply proved too much to overcome.

This battle and the entire experience with the Dragon Splinter has opened up a brand new line of thinking. I can see that the Dragons, while more complicated to play and costly, can open up an entire new array of possible strategies! I absolutely plan on taking full advantage of this splinter as I continue to move up the ranks and acquire new cards. The Dragon Splinter alone takes the strategy of this game to a whole new level!
