DisguisedToast made the promise to his viewers, confident that after a fifteen-hour session the odds would surely be in his favor in finding the rare Pokémon variant. He was incorrect in the end and spent $5,000 to be distributed seemingly at random to his own viewers through subscriptions.
Gave out $5000 worth of subs because I can't FIND A GOD DAMN SHINY WOOLOO AFTER 15 HOURS.— Disguised Toast (@DisguisedToast) November 18, 2019
It's not over though, I'm not giving up.
Shiny Pokémon do not confer any competitive advantages over regular Pokémon, they are simply rare in their colors and highly sought after by collectors purely for being rare. In previous games, the odds of finding a shiny Pokémon were abysmally low, but subsequent sequels have added ways in which players can change the odds in their favor.
For those who may not be familiar with techniques to catch shiny Pokémon, there are a few things one can do to increase their chances. For starters, catching 25 of only one specific Pokémon enables catch combos, drastically improving the odds of locating from from 1/4096 to 1/2048.
Battle count is also important and measured by how many of that same specific Pokémon you have fought. Battling 100 of one species of Pokémon ups the odds of finding a shiny by an addition 2.5%, and this can be tracked inside the Pokédex. Finally, using a Shiny Charm in combination with the above noted methods will bring the odds down to roughly 1/455.
It is not yet clear if DisguisedToast had all three bonuses in play, but one would imagine with 1,000 subscriptions on the line, he would have done his best to ensure his chances were as good as they could be. Viewers will likely see DisguisedToast in another session soon enough in his quest to find the elusive shiny Pokémon, and since the process is statistics-based, he is likely to find one in the long run.
DisguisedToast has been taking a break from the other games he streams, which mainly consists of Teamfight Tactics and recently a return to Hearthstone following the introduction of the new auto battler mode, Battlegrounds.
Given how popular the newest Pokémon is, he is one of many streamers who have temporarily turned to the game, though we should see him back at Teamfight Tactics soon, since he is continually practicing and competing at the highest levels of play.
