Hi I am asking if my team is good, my tean is Giratina lv.100 Rayquaza..

Your team looks great! I would rate it 10/10! The only thing that would make it better is when all of your Pokemon are Level 100.

Hope this helps!

Ignoring the level differences, I would give your team an 8/10 if all of them are legitimate, and a 5/10 if any are hacked. (I bring up legitimate vs hacked because two of your Pokemon are event only legendaries, and therefore are very prone to being hacked). If the movepools are poor (ie; Groudon has three Ground type moves, or if certain moves and move types are repeated too much), then subtract 3 from the score.

Your team has two Dragon types. 80% of your team is weak to Ice type attacks (Rayquaza even has a double weakness).

Legendaries are impressive, but are often seen as the easy way out when creating a team because they are so much stronger than other pokemon. Personally, I am not impressed by legendaries (I like more of a challenge).
