Just use Large Envelope (Flat) and you can send
1 oz for $2.05 and 20¢ for each additional oz
3 cards in a thick top loader is about 1/4 inch, and about 30 new topps cards are about 3/4 in a bubble envelope.
and if you use wider and longer bubble envelopes, you can put more cards in them,
Its worth a try
Sizes for Large Envelopes and Flats 
The Postal Service uses the word "flats" to refer to large envelopes, newsletters, and magazines. The words large envelopes and flats are used interchangeably. Whatever you call them, flats must:
Have one dimension that is greater than 6-1/8 inches high OR 11-½ inches long OR ¼ inch thick. Be no more than 12 inches high x 15 inches long x ¾ inch thick.
Dimension Minimum* Maximum Height 6-1/8 inches 12 inches Length 11-1/2 inches 15 inches Thickness 1/4 inch 3/4 inch
DMM 301 Physical Standards for Discount Flats
But to be a flat is must be flexible. That test would not be nice to baseball cards.
The PO will accept them - but they won't be liable for damage if the envelope is bent.
