Finally, time to continue, I've progressed a lot. Tate & Liza were the toughest gym leaders, as I expected them to be. It took ~20 tries to get the luck needed to win, had to teach Nidoran Blizzard to deal with the 2v1. I brought VOTE NIDO the level 2 Zigzagoon with me in the fight, since you NEED two Pokemon to start the fight, so he did absorb the Xatu's first attack, but that's just how it goes. These two are always terrible to fight in solo runs.
