Solgaleo

Great League: N/A

Solgaleo cannot be obtained in the Great League as its CP is too high

Ultra League: 1 / 5

Like most Legendary Pokemon, Solgaleo's stats are slightly on the lower end in the Ultra League due to its offensive slant. Solgaleo faces competition with other Steel-type options such as Galarian Stunfisk, Registeel, and Cobalion due to their stronger stats and superior movesets. Generally speaking, Solgaleo struggles against many top threats such as Giratina, Trevenant, Swampert, Charizard, and Jellicent, which leaves its impact generally lacking.

Master League: 4.5 / 5

Solgaleo is an excellent Pokemon to pair with your Dragon-type Pokemon. Thanks to its Steel / Psychic typing, Solgaleo is neutral to Fighting and thus fares much better against Zacian and Landorus-T compared to some other Steel-type options. Fire Spin is also synergistic with Dragon Breath / Dragon Tail, possessing nearly flawless coverage and applying immediate pressure to pesky Steel-type targets. It is a fair bit bulkier than Metagross and can easily avoid being 2HKOed by Zacian's Close Combat or Wild Charge. Lastly, Psychic Fangs is a great supporting move and can amplify the Dragons' already oppressive Fast Attack pressure.

With that said, Solgaleo can somewhat suffer from the "sim hero" syndrome, as its peak performance is reliant on its targets staying in and playing out the full one on one. Solgaleo's damage output requires ramping up and can struggle to be effective if the opponent has the option to switch. This can be tricky when dealing with Zacian and Dialga despite Solgaleo's overall advantage against them - both Pokemon can drop some high DPE self debuffing moves and then switch out to erase both their own self-inflicted debuffs and those from Psychic Fangs. Additionally, Solgaleo does not apply much shield pressure due to its relatively weak Charged Attacks. Lastly, Solgaleo suffers from a large range of common counters - Ho-Oh, Giratina-O, Kyogre, Groudon, and Yveltal, to name some.

As of this time of updating, Solgaleo's release is currently rather limited, although it can be traded as it is not a Mythical Pokemon. Getting a good IV one AND acquiring the Candy XL to max it out is an extremely daunting task for many players. It also requires 15 Attack IV to beat Zacian in CMP.
