Oxy the Haunter and Kolivan the Aegislash meet first. Keith is worried about Kolivan's weakness to ghost attacks. So, he'll switch to Brel the Meowstic. There is still a type weakness, but Brel has moves that can affect a Haunter's weakness to dark and psychic.
Brel will start with a Quick Guard to protect himself and then attempt to Charm Oxy's attack stat down. He'll refresh Quick Guard as needed through the fight when it wears off, and pepper in Charm a few more times as needed after every few moves, depending on how long the fight lasts. His main moves for attacking will be Psyshock, Psybeam, and Sucker Punch to take advantage of Oxy's type weaknesses. If Brel loses to Oxy, Keith will bring in Red the Torracat to continue. Red has a dark type move as well, and will spam Bite to finish Oxy off. If he's forced to bring in Kolivan against Oxy, Keith will use Retaliate as his first move, and then use Night Slash to take advantage of its dark typing.
If Emporio switches to Presto the Kadabra, and Brel is not fainted, Keith will continue to use Brel's dark type move, Sucker Punch for as long as he can. He will also continue to use the Quick Guard and Charm status strategy to protect Brel and lower Presto's attack stat. Should he not have Brel or loses Brel at this point, Keith will (continue to) use Red. In addition to Bite, Keith will add using Lick against Presto to take advantage of the ghost type weakness. He'll also throw in a few fire type moves in the hope of causing a burn status to help with dropping HP faster. Should he be in a position to have to use Kolivan here, he'll throw a Retaliate as the first move to take advantage of his previous Pokemon having fainted and then work on using Night Slash the most.
Keith will do his best to save Kolivan the Aegislash to use against Domino the Krokorok because Kolivan is resistant to rock type moves. He'll be using Sacred Sword the most because of its fighting type. Since Kolivan doesn't currently have King's Shield as a move, the Pokemon will be in Blade Forme through the battle. This leaves him weak in defense, but Keith is hoping a strong attack stat will take out the opponent fast enough to win. If Kolivan loses, Keith will lean towards bringing out Brel first if he has the choice, as Krokorok is resistant to fire typing and Torracat is weak to ground and rock, even though Meowstic is weak to dark. He would lean heavily on his Quick Guard and Charm strategy again here, sticking to his normal type moves and Sucker Punch to deal as much damage as possible. If he has to use Red, then he'd stick to Double Kick for Krokorok's weakness to fighting and fire type moves to try and force a burn status.
