u/No-Luck-Included

Maybe I'm not the most familiar with releases, but why is the Elf Wizard being released in 3 separate products, Orc Barbarian in 2, Elf Ranger in 2, and the Dwarf having the same model except one has a sword?

I understand that the first one is a Booster, but still, the Elf Wizard, the Elf Ranger. and the Orc Barbarian are the exact same model. Is this normal? Sorry if it is. I was just taken aback by it.
