Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
also how did you get porygon to work? i want to make a team around the thing, what kind of support does it need? ( im assuming you tested it cause you QC approved it)
Jirachi's more based around team support than actual sweeping, since hax and Steel + Fire coverage can only get you so far. Since Jirachi offers a load of resistances and paralysis support, it's pretty much a pivot Pokemon, but it can sweep in desperate situations.
I've always preferred it over SpD, so I should know.
