type teams have has an unfavorable match up vs Steel and Bug
-type Pokemon such as Celesteela and Heracross but
Z-Celebrate Victini
with its z celebrate set drastically improves this match up. With Z Celebrate, Victini gets +1 boost to its every stat which makes it not only a
big fast and powerful offensive threat but it also makes it very hard to revenge kill due to
boost to its
boosted defensive stats as victini has a respectable 100 /100 / 100 bulk. This set is a threat for steel type teams because there is no need for predicting Heatran switching in on a predicted Fire-type move against Victini which is a case if Victini
runs Choice Scarf or Choice Band sets is Choice locked, as locking Victini in an unfavorable move vs steel-type teams can prove bad for the team (talk specifically about being forced to have 50/50s with Heatran in the beginning of the sentence rather than this general statement). Heatran commonly runs offensive trapper set on steel-type teams and as a result Victini after Z Celebrate scores a guaranteed OHKO with focus blast on Heatran after stealth rock damage which makes the rest of the team very open to its fire stab move in searing shot and hence this set drastically pressures Steel-type teams
(This entire sentence is repetitive and unnecessary. Delete it and just say in the previous one that Victini cleans through the remainder of Steel with Searing Shot once Heatran faints).
(Add a sentence about how this set beats Bug as you mentioned it in the intro sentence). Latios is a great partner for Victini as with a Choice Scarf set, Latios can check Dragon-types for Victini and in return Victini deals with steel-types that Latios has trouble breaking past. Mega Gallade is also a good teammate as Victini appreciates the wall breaking prowess of Mega Gallade which allows Victini to clean teams easily after using Z Celebrate, the duo also forms a good Steel breaking core.
(I think you say a lot more than you need to with these two options, just keep it very brief. Latios is a revenge killer that can deal with Victini's common resistances, Mega Gallade forms an amazing Steel-breaking core with Victini, Jirachi sets SR on the field for Victini and spreads paralysis which gives Victini more opportunities to set up.)
