Ever since the introduction of the Dark Energy Crystals I'm having hard time winning. Hell, I've been losing since that day and this is the first daily quest that I've completed successfully.
I'm changing my SteemMonsters strategy now. I've sold most of my cards and I'm keeping just my favorite deck - the Water. A strange side benefit from doing so is that I'm always offered just the Water to play with :-)
The downside is that I'll be missing days playing the daily quests but since I'm missing it already since the recent changes it's not that much of a downside at all.
