Lastly, it's Lance, this will be the hardest battle. All of his Pokemon have Hyper Beam which can do a lot of damage! However, his Pokemon must then recharge so that gives you an opportunity to attack or revive/recover your Pokemon. Gyarados should be able to be taken down with an Electric attack as it 4x weak to it. The Dragonairs shouldn't be too hard to take down with a Ice attack. Aerodactyl is very fast! Use a Water or Electric attack, but it will most likely get an attack first. Dragonite is the real challenge. Safeguard means you won't be able to put any status effecr on it. Again, Dragonite is 4x weak to Ice but if its health gets too low Lance will use a Full Restore, so try to find a move which can do over half damage in one hit to finish it off. After beating Lance, you still have one more battle... the Champion! Enjoy it!
