@ FaZe Sky Blue isn't the color of the sky... but rather just a name for a pale light blue color i like. Similar to most blue eyes.
Both going for 2hko and winning 3 out of 4 rounds are respectable strategies. But i lean towards winning 3 out of 4 rounds. But i also take the 2hko when people give me the option. If someone spends all their pills going for a KO in round 2 always connect with that extra card if you can. Rather then KO in round 3. Also, Stay away from playing DRs to drag he game out. Worry more about winning rather than sticking to a specific strategy.
@ Mr Big. I always try to win. I don't think any of the penalty cards are worth it.
