Hello new friends! I'm Wham, and i've been playing this game for two years, since back when Karani cost less, did more, and was less squishy. I mostly rush with flame dawn decks, but at one point I learned the art of the OHKO, which i'm now known for.
I have a couple other guides, which I'm going to link to here once I find the actual links:
Analysis of Efficiency vs Cost of the card
Analysis of Ancient Egg
