Finally got one of my dream shinies - fire red Mewtwo. He has bold nature (not the best, but OK), and quite good IVs - 30/19/28/27/0/30. Shame about that Special Defense, but it doesn´t matter - especially since I was ABSOLUTELY unprepared for this hunt. I mean, my team consisted of lvl 47 Charizard, lvl 45 Raichu, lvl 45 Dragonair, lvl 46 Lapras and lvl 46 Aerodactyl, about 110 Ultra Balls and bunch of Revives and Full Restores. How did I get it, you ask?
Mewtwo in FR/LG is at lvl 70, with Safeguard, Swift, Psychic and Recover. The biggest problem was Psychic - it OHKOED all my team. My way around it? Charizards Smokescreen. I just needed the first attack to be anything else than Psychic (which was 75% chance). It worked. I managed to get 2 smokescreens onto him, before Psychic hit. Then I tried to paralyze it with Raichus Thunder wave, but Mewtwo outsped, and the Quick Claw Raichu was holding didn´t activate, and before I got to attack, it used Safeguard. So I decided to revive Charizard and resume Smokecsreenin. I managed to land another four, and after he went down to Swift (which was 2 or 3 hit KO), his Safeguard ended and I managed to paralyze him. Great.
Now I tried to damage him, to which Charizards Flamethrower proved the best (as I later found out it was thanks to it´s terrible Special Defense IV´s). But there showed antoher problem - thanks to Pressure it was quickly draining Flamethrowers PP, and it had Recover. And nothing else did enough damage. So in the end I didn´t have another option then throw Ultra Balls at paralyzed full health Mewtwo and hope one of them would work before it Struggles itself to death or I ran out of Ultra Balls.
Let me tell you, it was terrible. I mean, it was pretty easy to stall, since it soon run out of Psychic and Aerodactyl resists Swift, the only other damaging move, but it simply wouldn´t catch. After a while, it began to Struggle - and I realized something - it did very little recoil damage, and more importantly, it´s accuracy was affected by Smokescreen Charizard chugged at him previously. So, great, it did give me more time. But it didn´t give me more Ultra Balls. Finally, I managed to catch it - with only 32 Ultra Balls left. Yep, I threw over 70 Ultra Balls, before I caught him. But it was worth it. Next time I go shiny hunting legendary I will prepare better, tough. Lesson definitely learned.
Now if you excuse me, I will go and try to calm my fast-beating heart.
