hello ragazzo, nice team you've got here. i see you're using a combination of fire and fighting types to eliminate steels that would otherwise wall a late game sweep of CB stoutland. i'd like to suggest some changes to help this team out with that:
first thing that i noticed is that you have the infamous keldeo + tyranitar combination, but you aren't using them right. tyranitar wants a choice band, with enough speed to speed creep skarmory. being able to eliminate jellicent/lati@s/celebi is pretty important so that keldeo can spam its STAB attacks unhindered. tyranitar isn't accomplishing much with ice punch, since everything that it hits super effectively is hit harder with either stone edge or crunch. here's the set i recommend:
this set allows tyranitar to outrun all versions of jellicent that invest in less than 100 Spe EVs, meaning you can KO jelli before it hits you with will-o-wisp. it maintains tyranitar's incredible power while also offering natural bulk. the last slot is entirely dependent on you. superpower allows you to maim ferrothorn and rotom-w, as well as KO'ing breloom on the switch in. however, earthquake makes sure that jirachi can't set up on you, as well as being a solid answer against heatran. if you aren't satisfied with either of these and want to use something completely different, you can use ice beam. lando-t (which is becoming increasingly popular in usage) will usually switch into tyranitar without even thinking twice. however, with 56 SpA EVs, tyranitar KOs landorus-therian with ice beam after stealth rock 100% of the time. here's the set below if you wanna try it out:
now, as for keldeo, he's going to want a choice scarf. as others have mentioned you have no reliable revenge killer, and keldeo excels at just that. here's the set below:
once tyranitar has eliminated keldeo's checks and counters, you can feel free to spam hydro pump/secret sword. surf is a safer alternative to hydro pump when you can't afford to miss. hidden power ice becomes really useful when you have to revenge kill that +1 dragonite/salamence/haxorus, and is also useful for destroying thunderus-t.
finally, i can see that you have no pokemon to set up stealth rock, and stealth rock is probably the most important thing a team can have. because of this, i'm going to suggest you replace your gliscor with a very similar pokemon: landorus-t. thanks to intimidate, it is able to sponge physical hits like its nothing, and because of that 145 base atk it can hurt things without the use of swords dance-- unlike gliscor. moreover, it is a better pivot than gliscor because landorus-t can utilize u-turn more effectively. here's the set:
landorus-t is a great defensive pivot, and a great setter of stealth rock. the choice of nature is up to you; i prefer impish because it further buffs his defense stat, however relaxed can be used to make sure you have a slower u-turn than other landorus-t's, meaning you will always maintain the momentum in mirror matchups. earthquake and stone edge form the infamous edgequake combo, however hp ice can be used if you want to be able to hit garchomp/dragonite/salamence/opposing landorus-t once you've intimidated them. note however, that this leaves you more open against gyarados.
those are all the changes i can think of at this moment, hope i helped! good luck with the team
