New hero bundles. Usually consist of hero, skin or hero, skin, mount. Remain 14 days.
Seasonal or event bundles. Usually stay for several weeks, end date does get communicated.
Tournament bundles. For big tournaments, final winners selection of heroes and skins as a bundle. Available a week or two. Also seperate tournament mount with the team colors.
One or two basic bundles like the Nexus Conqueror. Stay for eternity +- 2 weeks.
