Excuse the late response everyone. After losing to a complete newbie in the tournament in the first round, losing to icb 3-1, and then losing to pikachufan 3-0, I figured I could use a little break from Elements. Thus, please excuse any mistakes since I'm recalling all of the duels that took place about twelve hours ago.
Pikachufan sums up the battles pretty well. I can only blame so much bad luck on the RNG Gods though, he just had the better decks.
Game 1 - (Lost)
Tried out my TU/Charger deck, only I drew five Chargers in my opening hand and only 1 Pendulum. Ouch. I
think he Lightning'd and threw various other control cards at my Chargers, so I never dealt enough damage.
Game 2 - (Lost)
Went with TU/Crimson Dragon/Cremation deck. I drew 4 Cremations in the opening hand, a single Dragon, and only 1 Pendulum, along with a few TU's thrown in. At this point, Pikachufan just played his cards and punched my face in.
Game 3 - (Lost)
I tried to use my Fractal/Pest/Vampire deck, which, again, works great under most conditions. However, I didn't draw a Pest (which, apparently, Pests don't like me to draw them), and I was forced to Fractal the Vampires instead. Even though I had counters to Dimensional Shield in the deck, I didn't draw them, and lost accordingly.
GG pikachufan, you are underestimated no more.
