Well I feel like a complete ******. Traded the worst lvl 1 Galarian Slowbro for a lvl 100 hyper trained Zacian on the Pokemon Home GTS. If you're going to ask for any old rubbish, expect to get rubbish lol.
Update on Coalossal - Caught a 10 Attack IV Timid Gigantamax one, EV trained, pp uped it all and everything, only for Game Freak to add Max Soup to the game ONE DAY LATER, so you can Gigantamax anything that has a G-Max form.
I could have bred a better one - another 500,000 Pokedollars gone.... :(.
