Bronze best possible team composition possibly higher elo
This team composotion cannot be beat after lvl6 by any team composition because every champ compliments the team it is a great mix of aoe ap, burst ad, and dps ad. Between Sejuani's and Ammumu w aoe damage and full tank builds you will never lose team fights, also Sejuani q and Kalista ult synergize with Yasuo ult.
top: Gangplank critplank build never really falls behind statik shiv, Blood thirster, Infinity edge, yoummuo ghostblade, triforce, boots mid: Yasuo statik shiv, Infinity edge, Ravenous Hydra, Last Whisper, Guardian Angel, boots jungle: Ammumu skirm saber cinderhulk, Rylai's scepter, ThornMail(or Randuin's), Abyssal scepter, Guardian Angel(or ZZrot's portal), boots will not die ADC: Kalista Blood thirster, Runaan's hurricane, Yoummou ghostblade, last whisper, mercurial scimitar, boots Support: Sejuani Face of the Mountain, iron locket of the solari, Sightstone, Liandry torment, Sunfire cape, Warmogs, boots
Sejauni's w & e combo slows enemies for Kalista's to either q or e than q, Sejuani should save her q for dives or enemy gank attempts. When sejuani and kalista roam mid Kali should ult Sejauni to Midlaner followed by Yasuo's ult. GangPlank should always build critplank late game his q can 1 or 2 shot anything except tanks use his ult to turn gank attempts in his team's favor or to prevent enemies from escaping teamfights. Yasuo should play it safe until statik shiv and vampire scepter are built and then start the crit dance, late game there are now 3 chances to ult crit dance is almost insta death. as soon as you hit lvl 6 roam bottom The sejauni player should try to land a q for the knock up so yasuo can ult which should lead to a death followed by bot tower than dragon. everyone go back to base rinse and repeat mid lane. Ammumu should **always ** have the blue buff period he is reliant on it his w burns through mana. build completely tank and you still run through a lvl 3 gank can burn someones flash fast i take smite and ghost enemies wont be able to run away. Ammumu should try to lvl 3 gank for gangplank up top allowing gp to snowball fast.
I have yet to make it out of bronze so I do not know how it works in higher Elo I do know that it is almost a foolproof team comp. Want to say I only got this comp 3 but the results were ridiculous. In this comp the only champion I personally cannot play is Yasuo. I have carried games single handed with Ammumu as a jungler, Sejuani as support, and GP in every single role except jungle. As Kalista with a Alistar support we turned Yasuo into the carry post 6 lvl.
PS: If anyone anywhere thinks they can put together a better team composition let me hear with a build and strategy guide.
ideally you take lulu top because it is safe, leaving you able to pick any strong mids probably either Orianna or someone who can start a fight since that is really all the comp lacks so maybe an Annie (Windwall doesn't block no flash tibbers)
in ranked so your comp 99% time cant even happen, you gotta think how likely you are to get every champion your comp based on champion popularity too.
where you can't actually touch anyone due to every champ being mobile, you can't push due to waveclear and where anyone getting caught on your team is dead. They can simply just not group and splitpush all 3 lanes or roam as 5 to catch you out, then mobility out when you collapse. GP also is terribad without items, good luck against lane swaps. Yasuo's early game against Ahri isn't too bad, until you factor in the fact that Gragas has way better ganks than Amumu and is much more mobile, and can disengage Amumu ults.
this team has played 9 ranked 5v5 games undefeated but we came close against another team fight comp of
