gamma mtg cards the Magnet Warrior [DOR-003] Secret Rare Vigilance (Attacking doesnt cause this creature to tap.) Then draw a card for each creature you control with a counter on it Hulk, Gamma Goliath | Magic:

Seachrome Coast Land Seachrome Coast enters the battlefield tapped unless you control two or fewer other lands

So to answer the question, we dont usually care about types so much in sets where it isnt the highlight, but occasionally do think Oh, this typal deck will enjoy this and I will definitely be putting this in my personal Bria, Riptide Rogue otter-typal Commander deck

"Oversize cards" is not a "set" by the usual Magic definition, but I'd guess your online store categorizes them that way to make it clearer to customers they're buying an abnormal card

I want to highlight a big subset of these cant attack cards

Thats not to say there arent some great picks to be made here, of course
