Summon types rotate throughout the year. Each event has a different type of Summon, but Special Summon is usually thrown in as a "limited" type of deal in addition to another summon. Special Summon also has cards that aren't available anywhere else (i.e. Poison Claw, Jewel Girl, etc.)

If by "cards like these" you mean high buffers, then I would say they're usually available in every summon type after being introduced in a limited summon. They'll almost always be added to Premium Summon.

Box summon usually has limited cards (i.e. Megaera, Honey Bee, Fenrir, Icarus, etc.), but sometimes they will re-release previous limited cards.
