On the other hand, with sleeved cards - you can do a "direct" rifle by "cutting" one half of the deck directly into the other (looks a bit like the overhand shuffle, acts more like a riffle).

Something like the second method here ("smash"? Shuffle). Note that the riffle shuffle is also pretty easy with sleeved cards, you just need to modify the technique a bit.

I play a lot of Magic and usually I do this. It’s hard to riffle shuffle a double sleeved 99 card library.

Much easier with a 40 card Limited deck or even a 60 Constructed deck ;)
